+## Contribution Guidelines
+
+We welcome contributions to:
+
+1. Add a new feature to the library (guidance below).
+2. Improve our documentation and add examples to make it clear how to leverage the supervision library.
+3. Report bugs and issues in the project.
+4. Submit a request for a new feature.
+5. Improve our test coverage.
+
+### Contributing Features ✨
+
+Supervision is designed to provide generic utilities to solve problems. Thus, we focus on contributions that can have an impact on a wide range of projects.
+
+For example, counting objects that cross a line anywhere on an image is a common problem in computer vision, but counting objects that cross a line 75% of the way through is less useful.
+
+Before you contribute a new feature, consider submitting an Issue to discuss the feature so the community can weigh in and assist.
+
+### API Design Principles
+
+Supervision APIs should remain generic, composable, and predictable across model families. Before adding a new integration, annotator option, or data conversion method, check the existing `sv.Detections`, `sv.KeyPoints`, and annotator patterns and follow these principles:
+
+1. **Model integrations normalize raw external outputs into existing Supervision containers.** Use `sv.Detections` for detection, segmentation, and other instance-level predictions that include boxes, masks, class ids, confidence scores, or extra per-instance fields. Use `sv.KeyPoints` for standalone keypoint or pose predictions when keypoints exist independently of detection boxes (e.g. pure pose estimation, landmark detection on pre-cropped images). Use `Detections.keypoints` when keypoints are always co-incident with boxes from the same model — the field stores an `(n, K, 2)` or `(n, K, 3)` array where the optional third channel is per-point confidence in `[0, 1]`.
+2. **Do not add a `from_<model>` method when the model already returns a Supervision object.** `from_*` methods are for converting raw outputs from external packages such as Ultralytics, Transformers, Inference, or MediaPipe. If a model's `predict()` method already returns `sv.Detections`, keep that result type and store additional structured payloads in `detections.data` or `detections.metadata` using documented keys.
+3. **Annotators render data; filtering and visibility are container state.** Filtering by confidence, class id, tracker id, geometry, or custom data should happen before annotation through the container slicing APIs, for example `detections[detections.confidence > 0.7]` or `key_points[key_points.confidence > 0.5]`. Per-point presentation state, such as a `KeyPoints.visible` mask, may live on the container and be honored consistently by annotators.
+4. **Annotator constructor arguments should describe visual presentation, not model-quality gates.** Use constructor arguments for color, thickness, opacity, text, position, style, and generic visualization parameters such as sigma levels. Annotators may skip invalid geometry defensively, including missing points, zero-area boxes, non-finite coordinates, or points marked invisible on the container. They should not introduce confidence thresholds or model-specific quality gates as rendering options.
+
+## How to Contribute Changes
+
+First, fork this repository to your own GitHub account. Click "fork" in the top corner of the `supervision` repository to get started:
+
+![Forking the repository](https://media.roboflow.com/fork.png)
+
+![Creating a repository fork](https://media.roboflow.com/create_fork.png)
+
+Then, run `git clone` to download the project code to your computer.
+
+You should also set up `roboflow/supervision` as an "upstream" remote (that is, tell git that the reference Supervision repository was the source of your fork of it):
+
+```bash
+git remote add upstream https://github.com/roboflow/supervision.git
+git fetch upstream
+```
+
+Move to a new branch using the `git checkout` command:
+
+```bash
+git checkout -b <scope>/<your_branch_name> upstream/develop
+```
+
+The name you choose for your branch should describe the change you want to make and start with an appropriate prefix:
+
+- `feat/`: for new features (e.g., `feat/line-counter`)
+- `fix/`: for bug fixes (e.g., `fix/memory-leak`)
+- `docs/`: for documentation changes (e.g., `docs/update-readme`)
+- `chore/`: for routine tasks, maintenance, or tooling changes (e.g., `chore/update-dependencies`)
+- `test/`: for adding or modifying tests (e.g., `test/add-unit-tests`)
+- `refactor/`: for code refactoring (e.g., `refactor/simplify-algorithm`)
+
+Make any changes you want to the project code, then run the following commands to commit your changes:
+
+```bash
+git add -A
+git commit -m "feat: add line counter functionality"
+git push -u origin <your_branch_name>
+```
+
+Use conventional commit messages to clearly describe your changes. The format is:
+
+```
+<type>[optional scope]: <description>
+```
+
+Common types include:
+
+- `feat`: A new feature
+- `fix`: A bug fix
+- `docs`: Documentation only changes
+- `style`: Changes that do not affect the meaning of the code (white-space, formatting, etc)
+- `refactor`: A code change that neither fixes a bug nor adds a feature
+- `perf`: A code change that improves performance
+- `test`: Adding missing tests or correcting existing tests
+- `chore`: Changes to the build process or auxiliary tools and libraries
+
+Then, go back to your fork of the `supervision` repository, click "Pull Requests", and click "New Pull Request".
+
+![Opening a pull request](https://media.roboflow.com/open_pr.png)
+
+Make sure the `base` branch is `develop` before submitting your PR.
+
+On the next page, review your changes then click "Create pull request":
+
+![Configuring a pull request](https://media.roboflow.com/create_pr_submit.png)
+
+Next, write a description for your pull request, and click "Create pull request" again to submit it for review:
+
+![Submitting a pull request](https://media.roboflow.com/write_pr.png)
+
+When creating new functions, please ensure you have the following:
+
+1. Docstrings for the function and all parameters.
+2. Unit tests for the function.
+3. Examples in the documentation for the function.
+4. Created an entry in our docs to autogenerate the documentation for the function.
+5. Please share a Google Colab with minimal code to test a new feature or reproduce the issue whenever possible. Please ensure that Google Colab can be accessed without any restrictions.
+
+When you submit your Pull Request, you will be asked to sign a Contributor License Agreement (CLA) by the `cla-assistant` GitHub bot. We can only respond to PRs from contributors who have signed the project CLA.
+
+All pull requests will be reviewed by the maintainers of the project. We will provide feedback and ask for changes if necessary.
+
+PRs must pass all tests and linting requirements before they can be merged.
+
+## Installation for Contributors
+
+Before starting your work on the project, set up your development environment:
+
+1. **Clone your fork of the project:**
+
+    **Option A: Recommended for most contributors (shallow clone of develop branch):**
+
+    ```bash
+    git clone --depth 1 -b develop https://github.com/YOUR_USERNAME/supervision.git
+    cd supervision
+    ```
+
+    Replace `YOUR_USERNAME` with your GitHub username.
+
+    > **Note**: Using `--depth 1` creates a shallow clone with minimal history and `-b develop` ensures you start with the development branch. This significantly reduces download size while providing everything needed to contribute.
+
+    **Option B: Full repository clone (if you need complete history):**
+
+    ```bash
+    git clone https://github.com/YOUR_USERNAME/supervision.git
+    cd supervision
+    git checkout develop
+    ```
+
+2. **Set up the upstream remote:**
+
+    ```bash
+    git remote add upstream https://github.com/roboflow/supervision.git
+    git fetch upstream
+    ```
+
+3. **Create and activate a virtual environment:**
+
+    **On Linux/macOS:**
+
+    ```bash
+    python3 -m venv .venv
+    source .venv/bin/activate
+    ```
+
+    **On Windows:**
+
+    ```cmd
+    python -m venv .venv
+    .venv\Scripts\activate
+    ```
+
+4. **Install `uv`:**
+
+    Follow the instructions on the [uv installation page](https://docs.astral.sh/uv/getting-started/installation/).
+
+5. **Install project dependencies:**
+
+    ```bash
+    uv pip install -r pyproject.toml --group dev --group docs --extra metrics
+    ```
+
+6. **Verify the setup:**
+
+    ```bash
+    uv run pytest
+    ```
+
+## 🎨 Code Style and Quality
+
+### Pre-commit tool
+
+This project uses the [pre-commit](https://pre-commit.com/) tool to maintain code quality and consistency. Before submitting a pull request or making any commits, it is important to run the pre-commit tool to ensure that your changes meet the project's guidelines.
+
+Furthermore, we have integrated a pre-commit GitHub Action into our workflow. This means that with every pull request opened, the pre-commit checks will be automatically enforced, streamlining the code review process and ensuring that all contributions adhere to our quality standards.
+
+To run the pre-commit tool, follow these steps:
+
+1. **Install pre-commit** (already included if you followed the installation steps above):
+
+    ```bash
+    uv sync --group dev
+    ```
+
+2. **Navigate to the project's root directory** (if not already there).
+
+3. **Run pre-commit checks**:
+
+    ```bash
+    uv run pre-commit run --all-files
+    ```
+
+    This will execute the pre-commit hooks configured for this project. If any issues are found, the pre-commit tool will provide feedback on how to resolve them. Make the necessary changes and re-run the command until all issues are resolved.
+
+4. **Install pre-commit as a git hook** (optional but recommended):
+
+    ```bash
+    uv run pre-commit install
+    ```
+
+    This will automatically run pre-commit checks every time you make a `git commit`.
+
+### Docstrings
+
+All new functions and classes in `supervision` should include docstrings. This is a prerequisite for any new functions and classes to be added to the library.
+
+`supervision` adheres to the [Google Python docstring style](https://google.github.io/styleguide/pyguide.html#383-functions-and-methods). Please refer to the style guide while writing docstrings for your contribution.
+
+Every docstring should include a usage example. When the example only uses `supervision`, NumPy, and the standard library — no optional extras, no external files or network access — strongly prefer `>>>` doctest format so it is automatically verified by the test suite. See [Doctests](#doctests) below for syntax guidance and for when fenced ```` ```python ```` blocks are appropriate instead.
+
+### Type checking
+
+Type hints are required on all new code. mypy is enforced by the pre-commit hook configured in `.pre-commit-config.yaml` — your PR will fail CI if mypy reports errors.
+
+### Readability
+
+Avoid multi-branch conditional expressions inside function or constructor arguments. If an argument needs more than a simple `a if condition else b`, assign it to a named local variable before the call.
+
+### Performance
+
+- Avoid unnecessary copies of NumPy arrays.
+- Prefer vectorized operations over Python loops in hot paths.
+- Lazy-import heavy framework dependencies (`torch`, `transformers`, `ultralytics`) inside the function that needs them — never at module top level.
+
+### Deprecation policy
+
+**Minimum window**: deprecated APIs must remain for at least **3 minor releases** before removal. Example: deprecated in `0.29.0` → removed in `0.32.0`.
+
+Use the appropriate mechanism depending on what is being deprecated:
+
+- **Module-level alias**: `supervision.utils.internal.warn_deprecated` in the deprecated module's `__init__.py`
+- **Renamed parameter**: `supervision.utils.internal.deprecated_parameter` decorator
+- **Public function, method, or class**: `@deprecated` from `pydeprecate`
+
+Always specify both the deprecation version and the planned removal version in the message or decorator arguments.
+
+### Deprecated module aliases
+
+`supervision.keypoint` is deprecated since `0.27.0` and will be removed in `0.30.0`. Always import from `supervision.key_points`:
+
+```python
+from supervision.key_points import KeyPoints  # correct
+```
+
+## 📝 Documentation
+
+The `supervision` documentation is stored in a folder called `docs`. The project documentation is built using `mkdocs`.
+
+To run the documentation locally:
+
+1. **Install documentation dependencies** (if not already installed):
+
+    ```bash
+    uv sync --group docs
+    ```
+
+2. **Start the documentation server**:
+
+    ```bash
+    uv run mkdocs serve
+    ```
+
+3. **Access the documentation** at `http://127.0.0.1:8000` in your browser.
+
+You can learn more about mkdocs on the [mkdocs website](https://www.mkdocs.org/).
+
+## 🧑‍🍳 Cookbooks
+
+We are always looking for new examples and cookbooks to add to the `supervision` documentation. If you have a use case that you think would be helpful to others, please submit a PR with your example. Here are some guidelines for submitting a new example:
+
+- Create a new notebook in the [`docs/notebooks`](https://github.com/roboflow/supervision/tree/develop/docs/notebooks) folder.
+- Add a link to the new notebook in [`docs/theme/cookbooks.html`](https://github.com/roboflow/supervision/blob/develop/docs/theme/cookbooks.html). Make sure to add the path to the new notebook, as well as a title, labels, author and supervision version.
+- Use the [Count Objects Crossing the Line](https://supervision.roboflow.com/develop/notebooks/count-objects-crossing-the-line/) example as a template for your new example.
+- Pin the version of `supervision` you are using in the notebook.
+- Place an appropriate "Open in Colab" button at the top of the notebook. You can find an example of such a button in the aforementioned `Count Objects Crossing the Line` cookbook.
+- **Notebook should be self-contained**. If you rely on external data (videos, images, etc.) or libraries, include download and installation commands in the notebook.
+- Annotate the code with appropriate comments, including links to the documentation describing each of the tools you have used.
+
+## 🧪 Tests
+
+[`pytest`](https://docs.pytest.org/en/7.1.x/) is used to run our tests.
+
+To run tests:
+
+```bash
+uv run pytest
+```
+
+To run tests with coverage:
+
+```bash
+uv run pytest --cov=supervision
+```
+
+### Test Structure
+
+Follow **Arrange-Act-Assert (AAA)**: one setup block, one action, one assertion group per test. Never put two independent actions in the same test.
+
+**Class grouping:** Group related tests into a class. The class name carries the unit under test; method names describe the expected outcome only — not the mechanism.
+
+```python
+class TestDetectionsWithNms:
+    def test_keeps_highest_confidence_detection(self): ...
+    def test_suppresses_lower_score_when_overlap_exceeds_threshold(self): ...
+    def test_raises_when_confidence_missing(self): ...
+```
+
+**Parametrize aggressively:** Three or more structurally identical tests should become a single `@pytest.mark.parametrize` case. Use `pytest.param(..., id="slug")` per case — not `ids=[...]` on the decorator — so the ID stays co-located with its arguments and survives reordering.
+
+```python
+@pytest.mark.parametrize(
+    ("overlap_metric", "expected_keep"),
+    [
+        pytest.param(OverlapMetric.IOU, [True, True], id="iou-keeps-both"),
+        pytest.param(OverlapMetric.IOS, [True, False], id="ios-suppresses-small"),
+    ],
+)
+def test_overlap_metric_determines_suppression(
+    overlap_metric: OverlapMetric, expected_keep: list[bool]
+) -> None:
+    """Small box inside large: IOU keeps both; IOS suppresses small."""
+    ...
+```
+
+**Docstrings:** Every test function/method requires at minimum a one-line docstring (within the project line length configured in `pyproject.toml`). Describe the scenario, not the implementation.
+
+### Doctests
+
+**Guidance:** when an example uses only `supervision`, NumPy, and the standard library — no optional extras (e.g. no `--extra metrics` packages), no external files, no network, no devices — prefer `>>>` doctest format so it is automatically verified by the test suite. Fenced ```` ```python ```` blocks are appropriate when the example cannot reasonably be executed (e.g. loading a third-party model, reading a video file) or when the primary purpose is demonstrating error/exception behaviour rather than return values.
+
+Doctests run automatically as part of the test suite via `--doctest-modules` in `pyproject.toml`. The `ELLIPSIS` and `NORMALIZE_WHITESPACE` flags are enabled globally, so `...` matches any output fragment and minor whitespace differences are ignored.
+
+```bash
+uv run pytest --doctest-modules src/
+```
+
+**Writing a doctest**
+
+Use the `Example:` section of a Google-style docstring. Prefix each input line with `>>>` and each continuation line with `...`. Place expected output immediately after the last input line with no blank line between them.
+
+```python
+def clip_boxes(xyxy: np.ndarray, resolution_wh: tuple) -> np.ndarray:
+    """Clip bounding boxes to frame boundaries.
+
+    Args:
+        xyxy: Box coordinates as (N, 4) float array.
+        resolution_wh: Frame size as (width, height).
+
+    Returns:
+        Clipped boxes as (N, 4) float array.
+
+    Example:
+        >>> import numpy as np
+        >>> import supervision as sv
+        >>> boxes = np.array([[-10, -5, 120, 80]], dtype=np.float32)
+        >>> sv.clip_boxes(boxes, resolution_wh=(100, 60))
+        array([[ 0.,  0., 100.,  60.]], dtype=float32)
+    """
+```
+
+### Key rules
+
+- **Single-line expression** — write the repr as expected output: `>>> len(result)` → `1`
+- **Multi-line statement** — use `...` continuation: `>>> arr = np.array([` / `...     [1, 2],` / `... ])`
+- **Print output** — write the printed string as expected output (no quotes).
+- **`None` return** — no output line needed (suppress with assignment or `_ =`).
+- **Large/variable arrays** — use `ELLIPSIS`: `array([...])` matches any content.
+- **`# doctest: +SKIP`** — use only as a last resort for genuinely non-runnable lines (e.g. a GPU-only call inside an otherwise runnable example). Prefer splitting the example into two blocks instead.
+
+Fenced ```` ```python ```` blocks remain appropriate for:
+
+- Examples that import optional extras (`supervision[metrics]`, `torch`, `ultralytics`).
+- Examples that read files, capture video, or require a running service.
+- Illustrative pseudocode that is intentionally incomplete.
+
+## 🔍 PR Review Guidelines

+Use **n/5 scoring** with inline code comments for specifics:
+
+**Code Quality (n/5):**
+
+- 5/5 🟢 Excellent — 4/5 🟢 Good — 3/5 🟡 Acceptable — 2/5 🟠 Needs Work — 1/5 🔴 Poor
+- Check: correctness (edge cases, None checks, bounds), Python best practices (idiomatic patterns, error handling, type hints), project conventions (docstrings, linting, import order, PEP 8 naming)
+
+**Testing (n/5):**
+
+- 5/5 🟢 Comprehensive — 4/5 🟢 Good — 3/5 🟡 Adequate — 2/5 🟠 Insufficient — 1/5 🔴 Missing
+- Verify: unit tests for new code, edge cases covered, specific assertions, realistic scenarios, clear test names
+
+**Documentation (n/5):**
+
+- 5/5 🟢 Excellent — 4/5 🟢 Good — 3/5 🟡 Adequate — 2/5 🟠 Insufficient — 1/5 🔴 Missing
+- Confirm: docstrings for public functions/classes, parameters/returns/exceptions documented, usage examples, mkdocs integration, changelog entry for user-facing changes
+
+### Risk Assessment
+
+Flag risks with severity (5/5 🔴 Critical — 4/5 🟠 High — 3/5 🟡 Medium — 2/5 🟢 Low — 1/5 🟢 Negligible):
+
+**Common risk categories:**
+
+1. **Breaking changes** — API changes, removed features, behavior modifications (must include migration guide)
+2. **Performance** — Inefficient algorithms, memory-intensive operations, bottlenecks
+3. **Compatibility** — New Python/dependency requirements, platform-specific code
+4. **Security** — Unvalidated input, code execution risks, data exposure
+
+### Review Summary Template
+
+```markdown
+## Review Summary
+
+**Recommendation:** [emoji] [Status] — [justification]
+
+**PR Completeness:**
+- ✅ Complete: [items]
+- ❌ Missing: [gaps]
+
+**Quality Scores:**
+- Code: n/5 [emoji] — [reason]
+- Testing: n/5 [emoji] — [reason]
+- Documentation: n/5 [emoji] — [reason]
+
+**Risk Level:** n/5 [emoji] — [description]
+
+**Critical Issues (Must Fix):**
+1. [Issue] — See comment on `file.py`
+
+**Suggestions (Optional):**
+1. [Improvement] — See suggestion on `file.py`
+
+**Next Steps:**
+1. [Action item]
+```
+
+### Review Best Practices
+
+**DO:** Use inline GitHub comments with suggestions, explain *why* (not just *what*), distinguish blocking vs. nice-to-have, acknowledge good work, run linter if needed (`uv run pre-commit run --all-files`)
+
+**DON'T:** Mention line numbers in summary (use inline comments), give vague feedback, nitpick style (defer to tools), assume knowledge of conventions, block on minor issues
+
+**Tone:** Be respectful, specific, pragmatic, and consistent. Focus on actionable feedback that moves PRs toward merge.

+# GitHub Copilot Instructions for Supervision
+
+This file provides context-aware guidance for GitHub Copilot when working in the Supervision repository.
+
+---
+
+## 📚 Repository Overview
+
+**Supervision** is a Python library providing reusable computer vision utilities for working with object detection models (YOLO, SAM, etc.). It offers tools for detections processing, tracking, annotation, and dataset management.
+
+- **Languages**: Python 3.10+
+- **Key Dependencies**: NumPy, OpenCV, SciPy
+- **License**: MIT
+
+---
+
+## 🏗️ Project Structure
+
+```
+supervision/
+├── src/
+│   └── supervision/     # Main library code
+│       ├── detection/   # Detection utilities
+│       ├── draw/        # Annotation and visualization
+│       ├── tracker/     # Object tracking
+│       ├── dataset/     # Dataset management
+│       └── utils/       # Shared utilities
+├── tests/               # Test suite (mirrors src/supervision/)
+├── docs/                # MkDocs documentation
+└── examples/            # Usage examples
+```
+
+---
+
+## 🔧 Development Commands
+
+**Setup:**
+
+```bash
+# Install dependencies
+uv sync --group dev --group docs --extra metrics
+
+# Install pre-commit hooks
+uv run pre-commit install
+```
+
+**Quality Checks:**
+
+```bash
+# Run all pre-commit hooks (formatting, linting, type checking)
+uv run pre-commit run --all-files
+
+# Run tests with coverage
+uv run pytest --cov=supervision
+```
+
+**Documentation:**
+
+```bash
+# Serve docs locally at http://127.0.0.1:8000
+uv run mkdocs serve
+```
+
+---
+
+## 💻 Code Conventions
+
+### General Guidelines
+
+- Follow **[AGENTS.md](../AGENTS.md)** for task-based development workflows
+- Reference **[CONTRIBUTING.md](CONTRIBUTING.md)** for detailed contribution guidelines
+- All code must pass `pre-commit` hooks before committing
+
+### Code Style
+
+- **Formatting**: Enforced by `ruff-format`, `prettier` (pre-commit)
+- **Linting**: Enforced by `ruff-check` (pre-commit)
+- **Type Hints**: Required on all new code
+- **Docstrings**: Required using [Google Python style](https://google.github.io/styleguide/pyguide.html#383-functions-and-methods)
+    - Must include usage examples with primitive values
+    - Serve as runnable documentation
+
+### Performance
+
+- Avoid unnecessary NumPy array copies
+- Prefer vectorized operations over Python loops
+- Use OpenCV operations efficiently
+
+### API Design
+
+- Follow existing naming patterns for consistency
+- Maintain backward compatibility unless explicitly breaking
+- Prefer functional utilities over complex classes
+
+---
+
+## 🧪 Testing Requirements
+
+All new features must include:
+
+- Unit tests covering happy path and edge cases
+- Tests for `None`, empty inputs, large arrays, boundary conditions
+- Clear test names describing what they validate
+- Proper assertions (not just "no exception raised")
+
+---
+
+## 📝 Documentation Requirements
+
+For new public functions/classes:
+
+- Google-style docstrings with parameters, returns, exceptions
+- Usage examples in docstrings
+- Entry in appropriate `docs/*.md` file
+- Reference in `mkdocs.yml` navigation
+
+---
+
+## 🔍 Pull Request Reviews
+
+**When reviewing PRs, follow the comprehensive [PR Review Guidelines](CONTRIBUTING.md#pr-review-guidelines).**
+
+Quick checklist:
+
+- Tests included and passing
+- Docstrings follow Google style with examples
+- Pre-commit hooks pass
+- Breaking changes documented
+- Score code quality, testing, docs (n/5 scale)
+- Use inline comments + GitHub suggestion format
+
+---
+
+## 🌿 Branching & Commits
+
+- Branch from `develop` using prefixes: `feat/`, `fix/`, `docs/`, `refactor/`, `perf/`, `test/`, `chore/`
+- Use **conventional commits**: `feat:`, `fix:`, `docs:`, `refactor:`, `perf:`, `test:`, `chore:`
+- All PRs target `develop` branch
+
+---
+
+## 🎯 Context-Aware Behavior
+
+- **For general development tasks**: Follow [AGENTS.md](../AGENTS.md)
+- **For pull request reviews**: Follow [PR Review Guidelines](CONTRIBUTING.md#pr-review-guidelines)
+- **For detailed processes**: Consult [CONTRIBUTING.md](CONTRIBUTING.md)

+# Agent Guidelines for `supervision`
+
+Behave like a senior contributor: precise, efficient, maintainable. When this file and [CONTRIBUTING.md](.github/CONTRIBUTING.md) conflict, **CONTRIBUTING.md wins**.
+
+---
+
+## 1. Before You Code
+
+- Read the task thoroughly; group clarifications into one ask.
+- Outline a plan before making changes.
+- Check whether the feature already exists under a different name.
+- Confirm alignment with `src/supervision/` architecture.
+
+---
+
+## 2. Repository Architecture
+
+**Package root**: `src/supervision/` — all library code. **Tests**: `tests/` — mirrors `src/supervision/`. **Public API**: `src/supervision/__init__.py`.
+
+```
+src/supervision/
+├── detection/
+│   ├── core.py          — Detections dataclass; all model connectors as classmethods
+│   ├── compact_mask.py  — compact mask representation
+│   ├── vlm.py           — VLM connectors (Florence-2, Gemini, Qwen, PaliGemma)
+│   ├── utils/           — pure NumPy helpers: boxes, converters, iou_and_nms, masks, polygons
+│   ├── line_zone.py     — LineZone
+│   └── tools/           — InferenceSlicer, PolygonZone, CSVSink, JSONSink, DetectionsSmoother
+├── annotators/core.py   — BoxAnnotator, MaskAnnotator, LabelAnnotator, … each: .annotate(scene, detections)
+├── key_points/          — KeyPoints, EdgeAnnotator, VertexAnnotator (use this, NOT keypoint/ — see §4)
+├── tracker/             — DEPRECATED
+├── dataset/core.py      — DetectionDataset / ClassificationDataset (YOLO / COCO / Pascal VOC)
+├── geometry/core.py     — Point, Rect, Vector, Position
+├── metrics/             — mAP, confusion matrix (requires --extra metrics)
+├── utils/internal.py    — warn_deprecated, deprecated_parameter, internal helpers
+└── config.py            — string constants; always import from here, never use literals
+```
+
+### Key design patterns
+
+- **`Detections` is the lingua franca** — every connector, tracker, and annotator speaks `Detections`. New connector = `@classmethod from_<framework>(cls, result) -> Detections`.
+- **Annotators are composable** — receive `scene` (BGR `np.ndarray`) + `detections`, return annotated copy.
+- **`data` dict extensibility** — per-detection metadata in `detections.data` as `np.ndarray` aligned with `xyxy`. Keys are constants from `config.py`.
+- **Vectorized throughout** — NumPy arrays, no Python loops in hot paths. Never write `for det in detections`.
+- **Lazy-import heavy deps** — `torch`, `transformers`, `ultralytics` must be imported inside the function that needs them, never at module top level.
+
+---
+
+## 3. Agent-Critical Rules
+
+These supplement [CONTRIBUTING.md](.github/CONTRIBUTING.md) — covering gaps or agent-specific failure modes.
+
+**Doc headings**: `###` max in docstrings and docs. `####` renders identically to bold in mkdocs — use `**bold**` instead.
+
+**Type hints**: required on all new code. mypy is enforced by pre-commit (`.pre-commit-config.yaml`).
+
+**Function docstrings**: every new or modified function, including private helpers and tests, must have a succinct docstring explaining its purpose. Put function-level why/what/how context inside the function docstring, not in a comment before the function. Public APIs still require the full Google-style structure described below.
+
+**Readable argument lists**: do not put multi-branch conditional expressions inside function or constructor arguments. If an argument needs more than a simple `a if condition else b`, assign it to a named local variable before the call.
+
+**Inline comments**: write code so the intent is clear from names, small helpers, and straightforward control flow. For non-trivial logic inside a function that still needs context, add concise inline comments explaining why the code exists, what invariant it protects, and how the tricky part works. Do not put comments before functions; use the function docstring instead. Do not comment obvious assignments, mechanical plumbing, lint-only changes, typing-only changes, or pure docs edits.
+
+**Doctest determinism** — output must be reproducible across platforms:
+
+- Use `# doctest: +ELLIPSIS` for floats that vary by platform.
+- Seed any RNG before calling it.
+- Never assert `dict` or `set` iteration order.
+- No network or filesystem access outside `supervision/assets/`.
+
+**⚠ Test structure** — agents frequently fail here; read [CONTRIBUTING.md §Tests](.github/CONTRIBUTING.md#-tests) carefully: AAA structure, class grouping, parametrize with `pytest.param(..., id="slug")`, one-line docstring per test.
+
+For branching, commit, code style, and API design conventions see [CONTRIBUTING.md](.github/CONTRIBUTING.md).
+
+---
+
+## 4. Deprecated Module Aliases
+
+`supervision.keypoint` deprecated since `0.27.0`, removed in `0.31.0`. Always import from `supervision.key_points`, not `supervision.keypoint`.
+
+---
+
+## 5. Deprecating APIs
+
+**Minimum window**: deprecated APIs must remain for at least **3 minor releases** before removal. Example: deprecated in `0.29.0` → removed in `0.32.0`.
+
+- Module-level: `supervision.utils.internal.warn_deprecated` in the deprecated module's own `__init__.py`
+- Parameter renamed (old→new): `supervision.utils.internal.deprecated_parameter` decorator
+- Public function, method, or class: `@deprecated` from `pydeprecate`
+
+Always name the version introduced and the removal version:
+
+```python
+warn_deprecated("'foo' deprecated in `0.29.0`, removed in `0.32.0`. Use 'bar'.")
+```
+
+---
+
+## 6. Implementing Features
+
+- Minimal implementation; type hints and Google docstrings with usage examples.
+- Tests covering new functionality and edge cases (see [CONTRIBUTING.md §Tests](.github/CONTRIBUTING.md#-tests)).
+- Update docstrings and mkdocs entries as needed.
+- Update [docs/changelog.md](docs/changelog.md) for every functional change or bug fix, including user-visible behavior changes. Skip changelog entries for lint-only, type-only, formatting-only, and pure documentation-only changes.
+
+**Extending `Detections`**: store metadata in `detections.data` as `np.ndarray` aligned with `xyxy`; define the key as a constant in `config.py` (e.g. `CLASS_NAME_DATA_FIELD`, `ORIENTED_BOX_COORDINATES`).
+
+**New model connector** (`detection/core.py`):
+
+```python
+@classmethod
+def from_myframework(cls, result) -> "Detections":
+    import myframework  # noqa: F401 — lazy import
+
+    xyxy = ...  # (N, 4)
+    return cls(
+        xyxy=xyxy,
+        confidence=...,
+        class_id=...,
+        data={CLASS_NAME_DATA_FIELD: np.array([...])},
+    )
+```
+
+VLM connectors go in `detection/vlm.py`, not `core.py`.
+
+---
+
+## 7. Bugs & Refactoring
+
+**Bugs**: reproduce → write failing test → minimal fix → verify no regressions.
+
+**Refactoring**: preserve behavior and API; reduce duplication; avoid sweeping changes unless requested; apply §5 deprecation when removing public API.
+
+---
+
+## 8. Before You Commit
+
+```bash
+uv run pytest --cov=supervision
+uv run pre-commit run --all-files
+```
+
+Capture a baseline before changes to avoid introducing new failures:
+
+```bash
+STASH_BEFORE=$(git rev-parse refs/stash 2>/dev/null)
+git stash push --include-untracked
+uv run pytest -q 2>&1 | tee /tmp/baseline.txt
+[ "$(git rev-parse refs/stash 2>/dev/null)" != "$STASH_BEFORE" ] && git stash pop
+uv run pytest -q 2>&1 | tee /tmp/after.txt
+diff /tmp/baseline.txt /tmp/after.txt
+```
+
+Any test passing in baseline but failing after = blocker.

+
+## 👋 Hello
+
+**We are your essential toolkit for computer vision.** From data loading to real-time zone counting, we provide the building blocks so you can focus on building applications around your models. 🤝
+
+## 💻 Install
+
+Pip install the supervision package in a [**Python>=3.10**](https://www.python.org/) environment.
+
+```bash
+pip install supervision
+```
+
+Read more about conda, mamba, and installing from source in our [guide](https://roboflow.github.io/supervision/).
+
+## 🔥 Quickstart
+
+### Models
+
+Supervision was designed to be model agnostic. Just plug in any classification, detection, or segmentation model. For your convenience, we have created [connectors](https://supervision.roboflow.com/latest/detection/core/#detections) for the most popular libraries like Ultralytics, Transformers, MMDetection, or Inference. Other integrations, like `rfdetr`, already return `sv.Detections` directly.
+
+Install the optional dependencies for this example with `pip install pillow rfdetr`.
+
+```python
+import supervision as sv
+from PIL import Image
+from rfdetr import RFDETRSmall
+
+image = Image.open("path/to/image.jpg")
+model = RFDETRSmall()
+detections = model.predict(image, threshold=0.5)
+
+len(detections)
+# 5
+```
+
+<details>
+<summary>👉 more model connectors</summary>
+
+- inference
+
+    Running with [Inference](https://github.com/roboflow/inference) requires a [Roboflow API KEY](https://docs.roboflow.com/api-reference/authentication#retrieve-an-api-key).
+
+    ```python
+    import supervision as sv
+    from PIL import Image
+    from inference import get_model
+
+    image = Image.open("path/to/image.jpg")
+    model = get_model(model_id="rfdetr-small", api_key="ROBOFLOW_API_KEY")
+    result = model.infer(image)[0]
+    detections = sv.Detections.from_inference(result)
+
+    len(detections)
+    # 5
+    ```
+
+</details>
+
+### Annotators
+
+Supervision offers a wide range of highly customizable [annotators](https://supervision.roboflow.com/latest/detection/annotators/), allowing you to compose the perfect visualization for your use case.
+
+```python
+import cv2
+import supervision as sv
+
+image = cv2.imread("path/to/image.jpg")
+# Assuming detections are obtained from a model
+detections = sv.Detections(...)
+
+box_annotator = sv.BoxAnnotator()
+annotated_frame = box_annotator.annotate(scene=image.copy(), detections=detections)
+```

+Supervision provides a set of [utils](https://supervision.roboflow.com/latest/datasets/core/) that allow you to load, split, merge, and save datasets in one of the supported formats.
+
+```python
+import supervision as sv
+from roboflow import Roboflow
+
+project = Roboflow().workspace("WORKSPACE_ID").project("PROJECT_ID")
+dataset = project.version("PROJECT_VERSION").download("coco")
+
+ds = sv.DetectionDataset.from_coco(
+    images_directory_path=f"{dataset.location}/train",
+    annotations_path=f"{dataset.location}/train/_annotations.coco.json",
+)
+
+path, image, annotation = ds[0]
+# loads image on demand
+
+for path, image, annotation in ds:
+    # loads image on demand

+description: About Supervision, Roboflow's open-source Python library for building reusable computer vision workflows.
+---
+
+# About Supervision
+
+Supervision is an open-source Python library by Roboflow for building computer vision applications. It gives developers a model-agnostic toolkit for loading predictions, annotating images and video, tracking objects, counting detections in zones, processing datasets, and evaluating model performance.
+
+The project centers on a unified `Detections` API with converters for supported outputs from Ultralytics, Roboflow Inference, Hugging Face Transformers, SAM, Detectron2, MMDetection, YOLO-NAS, PaddleDet, NCNN, Azure AI Vision, and VLM parsers such as Florence-2, PaliGemma, Qwen VL, Gemini, DeepSeek VL 2, and Moondream. That common representation lets teams change models without rewriting annotation, filtering, tracking, dataset, or metrics code.
+
+Supervision is maintained by Roboflow and an open-source contributor community. The library is MIT licensed, developed in public on GitHub, and published on PyPI.

+# Deprecated
+
+These features are phased out due to better alternatives or potential issues in future versions. Deprecated functionalities are typically supported for multiple subsequent releases, providing time for users to transition to updated methods.
+
+- [`sv.ByteTrack`](https://supervision.roboflow.com/latest/trackers/#supervision.tracker.byte_tracker.core.ByteTrack) is deprecated in `supervision-0.28.0` in favour of `ByteTrackTracker` from the external [`trackers`](https://pypi.org/project/trackers/) package (`pip install trackers`). The update method is renamed from `update_with_detections()` to `update()`. Removal is planned for `supervision-0.31.0`.
+- `supervision.keypoint` module is deprecated in `supervision-0.27.0`; use `supervision.key_points` instead. It will be removed in `supervision-0.31.0`.
+- `create_tiles` in `supervision.utils.image` is deprecated in `supervision-0.27.0`. It will be removed in `supervision-0.31.0`.
+- `ensure_cv2_image_for_processing` in `supervision.utils.conversion` is deprecated in `supervision-0.27.0`. It will be removed in `supervision-0.31.0`.
+- Keypoint validation utilities in `supervision.validators` are deprecated in `supervision-0.27.0`. They will be removed in `supervision-0.31.0`.
+- `normalized_xyxy` argument in [`sv.denormalize_boxes`](https://supervision.roboflow.com/latest/detection/utils/boxes/#supervision.detection.utils.boxes.denormalize_boxes) is deprecated in `supervision-0.27.0` and renamed to `xyxy`. Passing `normalized_xyxy=` emits a `FutureWarning`; support will be removed in `supervision-0.31.0`.
+- `supervision.dataset.utils` import path for [`sv.rle_to_mask`](https://supervision.roboflow.com/latest/detection/utils/converters/#supervision.detection.utils.converters.rle_to_mask) and [`sv.mask_to_rle`](https://supervision.roboflow.com/latest/detection/utils/converters/#supervision.detection.utils.converters.mask_to_rle) is deprecated in `supervision-0.28.0`. These functions moved to `supervision.detection.utils.converters` and will be removed from `supervision.dataset.utils` in `supervision-0.31.0`.
+- `sv.LMM` enum is deprecated in `supervision-0.27.0` and will be removed in `supervision-0.31.0`. Use `sv.VLM` instead.
+- [`sv.Detections.from_lmm`](https://supervision.roboflow.com/latest/detection/core/#supervision.detection.core.Detections.from_lmm) classmethod is deprecated in `supervision-0.26.0` and will be removed in `supervision-0.31.0`. Use [`sv.Detections.from_vlm`](https://supervision.roboflow.com/latest/detection/core/#supervision.detection.core.Detections.from_vlm) instead.
+- `KeyPoints.confidence` is deprecated in `supervision-0.29.0`. Use `KeyPoints.keypoint_confidence` instead. It will be removed in `supervision-0.32.0`.
+- Public `validate_*` helper functions are deprecated in `supervision-0.29.0` and will be removed in `supervision-0.32.0`. Supervision internals now use private `_validate_*` helpers.
+
+# Removed
+
+### 0.27.0
+
+- `overlap_ratio_wh` parameter in [`sv.InferenceSlicer`](https://supervision.roboflow.com/latest/detection/tools/inference_slicer/) has been removed. Use the pixel-based `overlap_wh` parameter instead.
+- `overlap_filter_strategy` parameter in [`sv.InferenceSlicer`](https://supervision.roboflow.com/latest/detection/tools/inference_slicer/) has been removed. Use `overlap_strategy` instead.
+
+### 0.26.0
+
+- The `sv.DetectionDataset.images` property has been removed in `supervision-0.26.0`. Please loop over images with `for path, image, annotation in dataset:`, as that does not require loading all images into memory. Also, constructing `sv.DetectionDataset` with parameter `images` as `Dict[str, np.ndarray]` is deprecated and has been removed in `supervision-0.26.0`. Please pass a list of paths `List[str]` instead.
+- The name `sv.BoundingBoxAnnotator` is deprecated and has been removed in `supervision-0.26.0`. It has been renamed to [`sv.BoxAnnotator`](https://supervision.roboflow.com/0.22.0/detection/annotators/#supervision.annotators.core.BoxAnnotator).
+
+### 0.24.0
+
+- The `frame_resolution_wh ` parameter in [`sv.PolygonZone`](detection/tools/polygon_zone.md/#supervision.detection.tools.polygon_zone.PolygonZone) has been removed.
+- Supervision installation methods `"headless"` and `"desktop"` were removed, as they are no longer needed. `pip install supervision[headless]` will install the base library and harmlessly warn of non-existent extras.
+
+### 0.23.0
+
+- The `track_buffer`, `track_thresh`, and `match_thresh` parameters in [`ByteTrack`](trackers.md/#supervision.tracker.byte_tracker.core.ByteTrack) are deprecated and were removed as of `supervision-0.23.0`. Use `lost_track_buffer,` `track_activation_threshold`, and `minimum_matching_threshold` instead.
+- The `triggering_position ` parameter in [`sv.PolygonZone`](detection/tools/polygon_zone.md/#supervision.detection.tools.polygon_zone.PolygonZone) was removed as of `supervision-0.23.0`. Use `triggering_anchors` instead.
+
+### 0.22.0
+
+- `sv.Detections.from_roboflow` is removed as of `supervision-0.22.0`. Use [`Detections.from_inference`](detection/core.md/#supervision.detection.core.Detections.from_inference) instead.
+- The method `sv.Color.white()` was removed as of `supervision-0.22.0`. Use the constant `sv.Color.WHITE` instead.
+- The method `sv.Color.black()` was removed as of `supervision-0.22.0`. Use the constant `sv.Color.BLACK` instead.
+- The method `sv.Color.red()` was removed as of `supervision-0.22.0`. Use the constant `sv.Color.RED` instead.
+- The method `sv.Color.green()` was removed as of `supervision-0.22.0`. Use the constant `sv.Color.GREEN` instead.
+- The method `sv.Color.blue()` was removed as of `supervision-0.22.0`. Use the constant `sv.Color.BLUE` instead.
+- The method `sv.ColorPalette.default()` was removed as of `supervision-0.22.0`. Use the constant [`ColorPalette.DEFAULT`](utils/draw.md/#supervision.draw.color.ColorPalette.DEFAULT) instead.
+- `sv.BoxAnnotator` was removed as of `supervision-0.22.0`, however `sv.BoundingBoxAnnotator` was immediately renamed to `sv.BoxAnnotator`. Use [`BoxAnnotator`](detection/annotators.md/#supervision.annotators.core.BoxAnnotator) and [`LabelAnnotator`](detection/annotators.md/#supervision.annotators.core.LabelAnnotator) instead of the old `sv.BoxAnnotator`.
+- The method `sv.FPSMonitor.__call__` was removed as of `supervision-0.22.0`. Use the attribute [`sv.FPSMonitor.fps`](utils/video.md/#supervision.utils.video.FPSMonitor.fps) instead.

+```bash
+pip install "supervision[geotiff]"
+wget -O RGB.byte.tif https://raw.githubusercontent.com/rasterio/rasterio/main/tests/data/RGB.byte.tif
+```
+
+`InferenceSlicer` can read an open `rasterio` dataset window-by-window. This keeps large GeoTIFFs out of memory while passing each tile to the callback as an `(H, W, C)` NumPy array.
+
+```python
+import numpy as np
+import rasterio
+import supervision as sv
+
+
+def callback(tile: np.ndarray) -> sv.Detections:
+    h, w = tile.shape[:2]
+    return sv.Detections(
+        xyxy=np.array([[w * 0.25, h * 0.25, w * 0.75, h * 0.75]], dtype=float),
+        confidence=np.array([0.9]),
+        class_id=np.array([0]),

+)
+
+with rasterio.open("RGB.byte.tif") as dataset:
+    detections = slicer(dataset)
+
+print(len(detections))

+
+GeoTIFF inputs must use a projected coordinate reference system. Reproject geographic rasters before passing them to `InferenceSlicer`.

+description: Frequently asked questions about installing Supervision, supported computer vision models, datasets, tracking, metrics, and licensing.
+---
+
+# Frequently Asked Questions
+
+## What is Supervision?
+
+Supervision is an open-source Python library by Roboflow for computer vision workflows. It provides a unified `Detections` class with converters for supported object detection, segmentation, and VLM outputs.
+
+## How do I install Supervision?
+
+Install the base package with:
+
+```bash
+pip install supervision
+```
+
+Use the `metrics` extra when you need optional metric dependencies:
+
+```bash
+pip install "supervision[metrics]"
+```
+
+Sample asset utilities are part of the base package under `supervision.assets`.
+
+## Which object detection models work with Supervision?
+
+Supervision is model agnostic. `sv.Detections` includes converters for Ultralytics YOLO, Roboflow Inference, Hugging Face Transformers outputs, SAM, Detectron2, MMDetection, YOLO-NAS, PaddleDet, NCNN, Azure AI Vision, and VLM parsers including Florence-2, PaliGemma, Qwen VL, Gemini, DeepSeek VL 2, and Moondream. Keypoint outputs have separate `sv.KeyPoints` converters, including MediaPipe.
+
+## What can I do with Supervision?
+
+You can annotate images and video, filter detections, track objects, count objects in zones or across lines, load and convert datasets, evaluate models with detection metrics, and export predictions for downstream analysis.
+
+## How do I track objects across video frames?
+
+Assign persistent tracker IDs before visualization. The built-in `sv.ByteTrack` wrapper accepts `Detections` through `update_with_detections()`, but it is deprecated in favor of `ByteTrackTracker` from the external `trackers` package. After tracking, combine the output with annotators such as `sv.TraceAnnotator`, `sv.BoxAnnotator`, and `sv.LabelAnnotator`.
+
+## What dataset formats does Supervision support?
+
+For detection datasets, Supervision supports YOLO, COCO JSON, Pascal VOC, CreateML, and LabelMe. Use `DetectionDataset.from_yolo()`, `DetectionDataset.from_coco()`, `DetectionDataset.from_pascal_voc()`, `DetectionDataset.from_createml()`, or `DetectionDataset.from_labelme()` to load datasets, and the matching `as_*` methods to export them.
+
+## How do I count objects in a zone?
+
+Use `sv.PolygonZone` for arbitrary polygon regions and `sv.LineZone` for line-crossing counts. Line crossing requires `detections.tracker_id`, so run a tracker before calling the line zone trigger.
+
+## How do I benchmark a model?
+
+Install `supervision[metrics]`, then use `supervision.metrics.mean_average_precision.MeanAveragePrecision` for mAP and `sv.ConfusionMatrix` for confusion matrices. Accumulate predictions and ground-truth `Detections`, then call `compute()` to calculate metrics.
+
+## Is Supervision free to use?
+
+Yes. Supervision is free and open source under the MIT license.
+
+## Where is the source code?
+
+The source code is available at [github.com/roboflow/supervision](https://github.com/roboflow/supervision).

+
+# Benchmark a Model
+
+Have you ever trained multiple detection models and wondered which one performs best on your specific use case? Or maybe you've downloaded a pre-trained model and want to verify its performance on your dataset? Model benchmarking is essential for making informed decisions about which model to deploy in production.
+
+This guide will show an easy way to benchmark your results using `supervision`. It will go over:
+
+1. [Loading a dataset](#loading-a-dataset)
+2. [Loading a model](#loading-a-model)
+3. [Benchmarking Basics](#benchmarking-basics)
+4. [Running a Model](#running-a-model)
+5. [Remapping Classes](#remapping-classes)
+6. [Visual Benchmarking](#visual-benchmarking)
+7. [Benchmarking Metrics](#benchmarking-metrics)
+8. [Mean Average Precision (mAP)](#mean-average-precision-map)
+9. [F1 Score](#f1-score)
+10. [Bonus: Model Leaderboard](#model-leaderboard)
+
+This guide will use an instance segmentation model, but it applies to object detection, instance segmentation, and oriented bounding box models (OBB) too.
+
+A condensed version of this guide is available as a [Colab Notebook](https://colab.research.google.com/drive/1HoOY9pZoVwGiRMmLHtir0qT6Uj45w6Ps?usp=sharing).
+
+## Loading a Dataset
+
+Suppose you start with a dataset. Perhaps you found it on [Universe](https://universe.roboflow.com/); perhaps you [labeled your own](https://roboflow.com/how-to-label/yolo11). In either case, this guide assumes you know of a labelled dataset at hand.
+
+We'll use the following libraries:
+
+- `roboflow` to manage the dataset and deploy models
+- `inference` to run the models
+- `supervision` to evaluate the model results
+
+```bash
+pip install roboflow inference "supervision[metrics]"
+```
+
+Here's how you can download a dataset:
+
+```python
+from roboflow import Roboflow
+
+rf = Roboflow(api_key="<YOUR_API_KEY>")
+project = rf.workspace("<WORKSPACE_NAME>").project("<PROJECT_NAME>")
+dataset = project.version("<DATASET_VERSION_NUMBER>").download("<FORMAT>")
+```
+
+If your dataset is from Universe, go to `Dataset` > `Download Dataset` > select the format (e.g. `YOLOv11`) > `Show download code`.
+
+If labeling your own data, go to the [dashboard](https://app.roboflow.com/) and check this [guide](https://docs.roboflow.com/api-reference/workspace-and-project-ids) to find your workspace and project IDs.
+
+In this guide, we shall use a small [Corgi v2](https://universe.roboflow.com/model-examples/segmented-animals-basic) dataset. It is well-labeled and comes with a test set.
+
+```python
+from roboflow import Roboflow
+
+rf = Roboflow(api_key="<YOUR_API_KEY>")
+project = rf.workspace("fbamse1-gm2os").project("corgi-v2")
+dataset = project.version(4).download("yolov11")
+```
+
+This will create a folder called `Corgi-v2-4` with the dataset in the current working directory, with `train`, `test`, and `valid` folders and a `data.yaml` file.
+
+## Loading a Model
+
+Let's load a model.
+
+Select and instantiate the detection or segmentation model you want to benchmark. Supervision works with Roboflow Inference for both local and cloud-deployed models, as well as Ultralytics YOLO checkpoints. Choose the tab below that matches your preferred framework, then pass images to the loaded model during the evaluation loop.
+
+=== "Inference, Local"
+
+    Roboflow supports a range of state-of-the-art [pre-trained models](https://inference.roboflow.com/quickstart/aliases/) for object detection, instance segmentation, and pose tracking. You don't even need an API key!
+
+    Let's load such a model with inference [`inference`](https://inference.roboflow.com/).
+
+    ```python
+    from inference import get_model
+
+    model = get_model(model_id="yolov11s-seg-640")
+    ```
+
+=== "Inference, Deployed"
+
+    You can train and deploy a model without leaving the Roboflow platform. See this [guide](https://docs.roboflow.com/train/train/train-from-scratch) for more details.
+
+    To load a model, you can use inference:
+
+    ```python
+    from inference import get_model
+
+    model_id = "<PROJECT_NAME>/<MODEL_VERSION>"
+    model = get_model(model_id=model_id)
+    ```
+
+=== "Ultralytics"
+
+    Similarly to Inference, Ultralytics allows you to run a variety of models.
+
+    ```bash
+    pip install "ultralytics<=8.3.40"
+    ```
+
+    ```python
+    from ultralytics import YOLO
+
+    model = YOLO("yolo11s-seg.pt")
+    ```
+
+## Benchmarking Basics
+
+Evaluating your model requires careful selection of the dataset. Which images should you use?Let's go over the different scenarios.
+
+- **Unrelated Dataset**: If you have a dataset that was not used to train the model, this is the best choice.
+- **Training Set**: This is the set of images used to train the model. This is fine if the model was not trained on this dataset. Otherwise, **never** use it for benchmarking - the results will seem unrealistically good.
+- **Validation Set**: This is the set of images used to validate the model during training. Every Nth training epoch, the model is evaluated on the validation set. Often the training is stopped once the validation loss stops improving. Therefore, even while the images aren't used to train the model, it still indirectly influences the training outcome.
+- **Test Set**: This is the set of images kept aside for model testing. It is exactly the set you should use for benchmarking. If the dataset was split correctly, none of these images would be shown to the model during training.
+
+Therefore, an unrelated dataset or the `test` set is the best choice for benchmarking. Several other problems may arise:
+
+- **Extra Classes**: An unrelated dataset may contain additional classes which you may need to [filter out](https://supervision.roboflow.com/how_to/filter_detections/#by-set-of-classes) before computing metrics.
+- **Class Mismatch**: In an unrelated dataset, the class names or IDs may be different to what your model produces, you'll need to remap them, which is [shown in this guide](#running-a-model).
+- **Data Contamination**: The `test` set may not be split correctly, with images from the test set also present in `training` or `validation` set and used during training. In this case, the results will be overly optimistic. This also applies when **very similar** images are used for training and testing - e.g. those taken in the same environment, same lighting conditions, similar angle, etc.
+- **Missing Test Set**: Some datasets do not come with a test set. In this case, you should collect and [label](https://roboflow.com/annotate) your own data. Alternatively, a validation set could be used, but the results could be overly optimistic. Make sure to test in the real world as soon as possible.
+
+## Running a Model
+
+At this stage, you should have:
+
+- A dataset of labeled images to evaluate the model.
+- A model prepared for benchmarking.
+
+With these ready, we can now run the model and obtain predictions. We'll use `supervision` to create a dataset iterator, and then run the model on each image.
+
+=== "Inference"
+
+    ```python
+    import supervision as sv
+
+    test_set = sv.DetectionDataset.from_yolo(
+        images_directory_path=f"{dataset.location}/test/images",
+        annotations_directory_path=f"{dataset.location}/test/labels",
+        data_yaml_path=f"{dataset.location}/data.yaml",
+    )
+
+    image_paths = []
+    predictions_list = []
+    targets_list = []
+
+    for image_path, image, label in test_set:
+        result = model.infer(image)[0]
+        predictions = sv.Detections.from_inference(result)
+
+        image_paths.append(image_path)
+        predictions_list.append(predictions)
+        targets_list.append(label)
+    ```
+
+=== "Ultralytics"
+
+    ```python
+    import supervision as sv
+
+    test_set = sv.DetectionDataset.from_yolo(
+        images_directory_path=f"{dataset.location}/test/images",
+        annotations_directory_path=f"{dataset.location}/test/labels",
+        data_yaml_path=f"{dataset.location}/data.yaml",
+    )
+
+    image_paths = []
+    predictions_list = []
+    targets_list = []
+
+    for image_path, image, label in test_set:
+        result = model(image)[0]
+        predictions = sv.Detections.from_ultralytics(result)
+
+        image_paths.append(image_path)
+        predictions_list.append(predictions)
+        targets_list.append(label)
+    ```
+
+## Remapping classes
+
+Did you notice an issue in the above logic? Since we're using an unrelated dataset, the class names and IDs may be different from what the model was trained on.
+
+We need to remap them to match the dataset classes. Here's how to do it:
+
+```python
+def remap_classes(
+    detections: sv.Detections,
+    class_ids_from_to: dict[int, int],
+    class_names_from_to: dict[str, str],
+) -> None:
+    new_class_ids = [
+        class_ids_from_to.get(class_id, class_id) for class_id in detections.class_id
+    ]
+    detections.class_id = np.array(new_class_ids)
+
+    new_class_names = [
+        class_names_from_to.get(name, name) for name in detections["class_name"]
+    ]
+    predictions["class_name"] = np.array(new_class_names)
+```
+
+Let's also remove the predictions that are not in the dataset classes.
+
+=== "Inference"
+
+    Dataset class names and IDs can be found in the `data.yaml` file, or by printing `dataset.classes`.
+
+    ```python
+    import supervision as sv
+
+    test_set = sv.DetectionDataset.from_yolo(
+        images_directory_path=f"{dataset.location}/test/images",
+        annotations_directory_path=f"{dataset.location}/test/labels",
+        data_yaml_path=f"{dataset.location}/data.yaml",
+    )
+
+    image_paths = []
+    predictions_list = []
+    targets_list = []
+
+    for image_path, image, label in test_set:
+        result = model.infer(image)[0]
+        predictions = sv.Detections.from_inference(result)
+
+        remap_classes(
+            detections=predictions,
+            class_ids_from_to={16: 0},
+            class_names_from_to={"dog": "Corgi"},
+        )
+        predictions = predictions[np.isin(predictions["class_name"], test_set.classes),]
+
+        image_paths.append(image_path)
+        predictions_list.append(predictions)
+        targets_list.append(label)
+    ```
+
+=== "Ultralytics"
+
+    Dataset class names and IDs can be found in the `data.yaml` file, or by printing `dataset.classes`.
+
+    Each model will have a different class mapping, so make sure to check the model's documentation. In this case, the model was trained on the COCO dataset, with a class configuration found [here](https://github.com/ultralytics/ultralytics/blob/main/ultralytics/cfg/datasets/coco8.yaml).
+
+    ```python
+    import supervision as sv
+
+    test_set = sv.DetectionDataset.from_yolo(
+        images_directory_path=f"{dataset.location}/test/images",
+        annotations_directory_path=f"{dataset.location}/test/labels",
+        data_yaml_path=f"{dataset.location}/data.yaml",
+    )
+
+    image_paths = []
+    predictions_list = []
+    targets_list = []
+
+    for image_path, image, label in test_set:
+        result = model(image)[0]
+        predictions = sv.Detections.from_ultralytics(result)
+
+        remap_classes(
+            detections=predictions,
+            class_ids_from_to={16: 0},
+            class_names_from_to={"dog": "Corgi"},
+        )
+        predictions = predictions[np.isin(predictions["class_name"], test_set.classes),]
+
+        image_paths.append(image_path)
+        predictions_list.append(predictions)
+        targets_list.append(label)
+    ```
+
+## Visualizing Predictions
+
+The first step in evaluating your model’s performance is to visualize its predictions. This gives an intuitive sense of how well your model is detecting objects and where it might be failing.
+
+```python
+import supervision as sv
+
+N = 9
+GRID_SIZE = (3, 3)
+
+target_annotator = sv.PolygonAnnotator(color=sv.Color.from_hex("#8315f9"), thickness=8)
+prediction_annotator = sv.PolygonAnnotator(
+    color=sv.Color.from_hex("#00cfc6"), thickness=6
+)
+
+
+annotated_images = []
+for image_path, predictions, targets in zip(
+    image_paths[:N], predictions_list[:N], targets_list[:N]
+):
+    annotated_image = cv2.imread(image_path)
+    annotated_image = target_annotator.annotate(
+        scene=annotated_image, detections=targets
+    )
+    annotated_image = prediction_annotator.annotate(
+        scene=annotated_image, detections=prediction
+    )
+    annotated_images.append(annotated_image)
+
+sv.plot_images_grid(images=annotated_images, grid_size=GRID_SIZE)
+```
+
+Here, predictions in purple are targets (ground truth), and predictions in teal are model predictions.
+
+![Basic Model Comparison](https://media.roboflow.com/supervision/image-examples/how-to/benchmark-models/basic-model-comparison-corgi.png)
+
+!!! tip
+
+    Use `sv.BoxAnnotator` for object detection and `sv.OrientedBoxAnnotator` for OBB.
+
+    See [annotator documentation](https://supervision.roboflow.com/latest/detection/annotators/) for even more options.
+
+## Visual Benchmarking
+
+To inspect where a model succeeds and fails, pass `save_directory_path` to `sv.ConfusionMatrix.benchmark(...)`. For every dataset image it writes a 2x2 result grid — `Ground Truth`, `True Positives`, `False Positives`, and `False Negatives` panels — directly into that directory, reusing the original image filenames. This makes it easy to skim through per-image outcomes alongside the aggregate confusion matrix.
+
+```python
+import supervision as sv
+
+confusion_matrix = sv.ConfusionMatrix.benchmark(
+    dataset=test_set,
+    callback=callback,
+    save_directory_path="./results",
+)
+```
+
+## Benchmarking Metrics
+
+With multiple models, fine details matter. Visual inspection may not be enough. `supervision` provides a collection of metrics that help obtain precise numerical results of model performance.
+
+### Mean Average Precision (mAP)
+
+We'll start with [MeanAveragePrecision (mAP)](https://supervision.roboflow.com/latest/metrics/mean_average_precision/#supervision.metrics.mean_average_precision.MeanAveragePrecision), which is the most commonly used metric for object detection. It measures the average precision across all classes and IoU thresholds.
+
+For a thorough explanation, check out our [blog](https://blog.roboflow.com/mean-average-precision/) and [Youtube video](https://www.youtube.com/watch?v=oqXDdxF_Wuw).
+
+Here, the most popular value is `mAP 50:95`. It represents the average precision across all classes and IoU thresholds (`0.5` to `0.95`), whereas other values such as `mAP 50` or `mAP 75` only consider a single IoU threshold (`0.5` and `0.75` respectively).
+
+Let's compute the mAP:
+
+```python
+from supervision.metrics import MeanAveragePrecision, MetricTarget
+
+map_metric = MeanAveragePrecision(metric_target=MetricTarget.MASKS)
+map_result = map_metric.update(predictions_list, targets_list).compute()
+```
+
+Try printing the result to see it at a glance:
+
+```python
+print(map_result)
+```
+
+```
+MeanAveragePrecisionResult:
+Metric target: MetricTarget.MASKS
+Class agnostic: False
+mAP @ 50:95: 0.2409
+mAP @ 50:    0.3591
+mAP @ 75:    0.2915
+mAP scores: [0.35909 0.3468 0.34556 ...]
+IoU thresh: [0.5 0.55 0.6 ...]
+AP per class:
+  0: [0.35909 0.3468 0.34556 ...]
+...
+Small objects: ...
+Medium objects: ...
+Large objects: ...
+```
+
+You can also plot the results:
+
+```python
+map_result.plot()
+```
+
+![mAP Plot](https://media.roboflow.com/supervision/image-examples/how-to/benchmark-models/mAP-plot-corgi.png)
+
+The metric also breaks down the results by detected object area. Small, medium and large are simply those with area less than 32², between 32² and 96², and greater than 96² pixels respectively.
+
+### F1 Score
+
+The [F1 Score](https://supervision.roboflow.com/latest/metrics/f1_score/) is another useful metric, especially when dealing with an imbalance between false positives and false negatives. It’s the harmonic mean of **precision** (how many predictions are correct) and **recall** (how many actual instances were detected).
+
+Here's how you can compute the F1 score:
+
+```python
+from supervision.metrics import F1Score, MetricTarget
+
+f1_metric = F1Score(metric_target=MetricTarget.MASKS)
+f1_result = f1_metric.update(predictions_list, targets_list).compute()
+```
+
+As with mAP, you can also print the result:
+
+```python
+print(f1_result)
+```
+
+```
+F1ScoreResult:
+Metric target: MetricTarget.MASKS
+Averaging method: AveragingMethod.WEIGHTED
+F1 @ 50:     0.5341
+F1 @ 75:     0.4636
+F1 @ thresh: [0.53406 0.5278 0.52153 ...]
+IoU thresh: [0.5 0.55 0.6 ...]
+F1 per class:
+  0: [0.53406 0.5278 0.52153 ...]
+...
+Small objects: ...
+Medium objects: ...
+Large objects: ...
+```
+
+Similarly, you can plot the results:
+
+```python
+f1_result.plot()
+```
+
+![F1 Plot](https://media.roboflow.com/supervision/image-examples/how-to/benchmark-models/f1-score-corgi.png)
+
+As with mAP, the metric also breaks down the results by detected object area. Small, medium and large are simply those with area less than 32², between 32² and 96², and greater than 96² pixels respectively.

+
+## Frequently Asked Questions
+
+### How do I benchmark a model with supervision?
+
+Use `supervision.metrics.mean_average_precision.MeanAveragePrecision` — accumulate prediction and ground-truth `Detections` with `update(...)` and then call `compute()`. For confusion matrices, use `sv.ConfusionMatrix.from_detections(predictions=predictions, targets=targets, classes=classes)`.
+
+### What IoU thresholds does MeanAveragePrecision use?
+
+It computes mAP over IoU thresholds from 0.50 to 0.95 in steps of 0.05 (mAP@50:95), plus mAP@50 and mAP@75 individually.
+
+### Can I benchmark segmentation models?
+
+Yes, if you want to evaluate their bounding boxes. Convert model outputs to `Detections` and pass them to `MeanAveragePrecision.update(...)`; the current mAP path prepares COCO-style bounding boxes from `detections.xyxy`.
+
+### What is a ConfusionMatrix and how do I use it?
+
+`sv.ConfusionMatrix` visualizes true positives, false positives, and false negatives per class. Create one with `sv.ConfusionMatrix.from_detections(predictions=predictions, targets=targets, classes=classes, conf_threshold=0.5, iou_threshold=0.5)`, then call `confusion_matrix.plot()` to render a heatmap. If you want per-image validation visualizations saved to disk, pass `save_directory_path="./results"` to `sv.ConfusionMatrix.benchmark(...)`; it will write 2x2 result grids directly into that directory using the original image filenames, with `Ground Truth`, `True Positives`, `False Positives`, and `False Negatives` panels.

+
+With supervision, you can count the number of objects in a zone in an image or video. In this guide, we will show how to count the number of cars in a traffic video.
+
+[View the notebook that accompanies this tutorial](https://github.com/roboflow/notebooks/blob/main/notebooks/how-to-use-polygonzone-annotate-and-supervision.ipynb).
+
+To make it easier for you to follow our tutorial download the video we will use as an example. You can do this using the `supervision.assets` module:
+
+```python
+from supervision.assets import download_assets, VideoAssets
+
+download_assets(VideoAssets.VEHICLES_2)
+```
+
+## Initialize a Model and Load Video
+
+First, we need to initialize a model. Let's use a YOLOv8 model with the default COCO checkpoint. We also need to load a video on which to run inference.
+
+Create a YOLO model instance and download the source video. The model will process each frame during inference. A shared color palette ensures consistent zone coloring throughout the output video.
+
+```python
+import numpy as np
+import supervision as sv
+import cv2
+
+from ultralytics import YOLO
+from supervision.assets import VideoAssets, download_assets
+
+model = YOLO("yolov8s.pt")
+
+VIDEO = download_assets(VideoAssets.VEHICLES_2)
+
+colors = sv.ColorPalette.DEFAULT
+```
+
+## Calculate Coordinates
+
+To count objects in a zone, you need to know the coordinates where you want to draw the zone.
+
+You can calculate coordinates using the [PolygonZone web utility](https://roboflow.github.io/polygonzone/).
+
+To use the PolygonZone website, you will need to upload an image or frame from a video. You can retrieve a frame using this code:
+
+```python
+generator = sv.get_video_frames_generator(VIDEO)
+iterator = iter(generator)
+
+frame = next(iterator)
+
+cv2.imwrite("first_frame.png", frame)
+```
+
+PolygonZone will give you NumPy arrays that you can use with supervision to count objects in zones.
+
+<video width="100%" loop muted autoplay>
+  <source src="https://media.roboflow.com/polygonzone.mp4" type="video/mp4">
+</video>
+
+Save the coordinates in an array:
+
+```python
+polygons = [
+    np.array([[718, 595], [927, 592], [851, 1062], [42, 1059]]),
+    np.array([[987, 595], [1199, 595], [1893, 1056], [1015, 1062]]),
+]
+```
+
+## Define Zones
+
+With the coordinates of the zones to draw ready, we can set up our zones:
+
+Instantiate a `PolygonZone` for each polygon array, pairing it with a `PolygonZoneAnnotator` for visual overlay and a `BoxAnnotator` for drawing detection boxes. Each zone will later trigger on incoming detections to determine which objects fall inside its boundaries, enabling per-zone counting in the inference callback.
+
+```python
+zones = [sv.PolygonZone(polygon=polygon) for polygon in polygons]
+zone_annotators = [
+    sv.PolygonZoneAnnotator(
+        zone=zone,
+        color=colors.by_idx(index),
+        thickness=4,
+        text_thickness=8,
+        text_scale=4,
+    )
+    for index, zone in enumerate(zones)
+]
+box_annotators = [
+    sv.BoxAnnotator(
+        color=colors.by_idx(index),
+        thickness=4,
+    )
+    for index in range(len(polygons))
+]
+```
+
+## Run Inference
+
+We can run inference on a video using the [sv.process_video](https://supervision.roboflow.com/utils/video/#process_video) function. This function accepts a callback that runs inference on each frame and compiles the results into a video.
+
+Below, we can call our YOLOv8 model, annotate predictions and zones, then save the results to a file called `result.mp4`.
+
+```python
+def process_frame(frame: np.ndarray, i) -> np.ndarray:
+    results = model(frame, imgsz=1280, verbose=False)[0]
+    detections = sv.Detections.from_ultralytics(results)
+
+    for zone, zone_annotator, box_annotator in zip(
+        zones, zone_annotators, box_annotators
+    ):
+        mask = zone.trigger(detections=detections)
+        detections_filtered = detections[mask]
+        frame = box_annotator.annotate(scene=frame, detections=detections_filtered)
+        frame = zone_annotator.annotate(scene=frame)
+
+    return frame
+
+
+sv.process_video(source_path=VIDEO, target_path="result.mp4", callback=process_frame)
+```
+
+Here is an example of inference run on the video:

+<video width="100%" loop muted autoplay>

+
+## Frequently Asked Questions
+
+### How do I count objects in a zone with supervision?
+
+Create `sv.PolygonZone` with a polygon defining your region. Call `zone.trigger(detections)` on each frame — it returns a mask of detections inside the zone.
+
+### Can I count objects crossing a line instead of entering a zone?
+
+Yes. Use `sv.LineZone` — define a start and end point. `zone.trigger(detections)` returns a tuple of two boolean arrays, `(crossed_in, crossed_out)`, indicating which detections crossed the line in each direction. `LineZone` requires `detections.tracker_id`; run a tracker first so the same object can be matched across frames.
+
+### Can I combine zone counting with tracking?
+
+Yes. You can pass tracker IDs from `sv.ByteTrack` alongside your detections, but `sv.PolygonZone` still evaluates the zone on each frame and reports which objects are currently inside it. If you want to count each object only once when it first enters the zone, maintain a set of seen `tracker_id` values after filtering detections with `zone.trigger(detections)`, or use a dedicated entry/crossing counting tool such as `sv.LineZone` when it better matches your use case.

+    Don't have an image? Download the one used in this tutorial:
+
+    ```bash
+    wget https://media.roboflow.com/notebooks/examples/dog.jpeg

+Supervision provides a seamless process for annotating predictions generated by various object detection and segmentation models. This guide shows how to perform inference with the [Inference](https://github.com/roboflow/inference), [Ultralytics](https://github.com/ultralytics/ultralytics) or [Transformers](https://github.com/huggingface/transformers) packages. Following this, you'll learn how to import these predictions into Supervision and use them to annotate source image.
+
+![basic-annotation](https://media.roboflow.com/supervision_detect_and_annotate_example_1.png)
+
+## Run Detection
+
+First, you'll need to obtain predictions from your object detection or segmentation model.
+
+To run inference, initialize your chosen model and pass the source image to its predict or infer method. Supervision supports Roboflow Inference, Ultralytics YOLO, and Hugging Face Transformers -- select the tab matching your framework. The result is a framework-specific object you will convert to a `Detections` instance in the next step.
+
+=== "Inference"
+
+    ```python
+    import cv2
+    from inference import get_model
+
+    model = get_model(model_id="yolov8n-640")
+    image = cv2.imread("dog.jpeg")
+    results = model.infer(image)[0]
+    ```
+
+=== "Ultralytics"
+
+    ```python
+    import cv2
+    from ultralytics import YOLO
+
+    model = YOLO("yolov8n.pt")
+    image = cv2.imread("dog.jpeg")
+    results = model(image)[0]
+    ```
+
+=== "Transformers"
+
+    ```python
+    import torch
+    from PIL import Image
+    from transformers import DetrImageProcessor, DetrForObjectDetection
+
+    processor = DetrImageProcessor.from_pretrained("facebook/detr-resnet-50")
+    model = DetrForObjectDetection.from_pretrained("facebook/detr-resnet-50")
+
+    image = Image.open("dog.jpeg")
+    inputs = processor(images=image, return_tensors="pt")
+
+    with torch.no_grad():
+        outputs = model(**inputs)
+
+    width, height = image.size
+    target_size = torch.tensor([[height, width]])
+    results = processor.post_process_object_detection(
+        outputs=outputs, target_sizes=target_size
+    )[0]
+    ```
+
+## Load Predictions into Supervision
+
+Now that we have predictions from a model, we can load them into Supervision.
+
+Each supported framework has a dedicated class method on `sv.Detections` that converts raw model output into a unified Supervision object. Call `from_inference`, `from_ultralytics`, or `from_transformers` depending on the package you used for inference. This normalization step ensures all downstream annotators and filters work identically regardless of the source model.
+
+=== "Inference"
+
+    We can do so using the [`sv.Detections.from_inference`](https://supervision.roboflow.com/latest/detection/core/#supervision.detection.core.Detections.from_inference) method, which accepts model results from both detection and segmentation models.
+
+    ```{ .py hl_lines="2 8" }
+    import cv2
+    import supervision as sv
+    from inference import get_model
+
+    model = get_model(model_id="yolov8n-640")
+    image = cv2.imread("dog.jpeg")
+    results = model.infer(image)[0]
+    detections = sv.Detections.from_inference(results)
+    ```
+
+=== "Ultralytics"
+
+    We can do so using the [`sv.Detections.from_ultralytics`](https://supervision.roboflow.com/latest/detection/core/#supervision.detection.core.Detections.from_ultralytics) method, which accepts model results from both detection and segmentation models.
+
+    ```{ .py hl_lines="2 8" }
+    import cv2
+    import supervision as sv
+    from ultralytics import YOLO
+
+    model = YOLO("yolov8n.pt")
+    image = cv2.imread("dog.jpeg")
+    results = model(image)[0]
+    detections = sv.Detections.from_ultralytics(results)
+    ```
+
+=== "Transformers"
+
+    We can do so using the [`sv.Detections.from_transformers`](https://supervision.roboflow.com/latest/detection/core/#supervision.detection.core.Detections.from_transformers) method, which accepts model results from both detection and segmentation models.

+
+## Annotate Image with Detections
+
+Finally, we can annotate the image with the predictions. Since we are working with an object detection model, we will use the [`sv.BoxAnnotator`](https://supervision.roboflow.com/latest/detection/annotators/#supervision.annotators.core.BoxAnnotator) and [`sv.LabelAnnotator`](https://supervision.roboflow.com/latest/detection/annotators/#supervision.annotators.core.LabelAnnotator) classes.
+
+To draw bounding boxes and class labels on your image, create a `BoxAnnotator` and a `LabelAnnotator`, then call their `annotate` methods in sequence. Each annotator returns the modified image, so you can chain multiple annotators together. The result is a single NumPy array with all visual overlays rendered and ready for display or saving.

+
+By default, [`sv.LabelAnnotator`](https://supervision.roboflow.com/latest/detection/annotators/#supervision.annotators.core.LabelAnnotator) will label each detection with its `class_name` (if possible) or `class_id`. You can override this behavior by passing a list of custom `labels` to the `annotate` method.

+
+## Frequently Asked Questions
+
+### How do I detect and annotate objects with supervision?
+
+Pass any model's output to `sv.Detections.from_<model>()` to create a unified `Detections` object. Then pass it to `sv.BoxAnnotator` or `sv.MaskAnnotator` to draw predictions on an image.
+
+### Can I annotate both bounding boxes and masks at the same time?
+
+Yes. Chain annotators: first draw boxes with `BoxAnnotator`, then overlay masks with `MaskAnnotator` on the same scene.
+
+### How do I label detections with class names?
+
+Use `sv.LabelAnnotator` and pass custom text with the `labels` parameter. If a connector provides class names, they are stored in `detections["class_name"]` / `detections.data["class_name"]`; when `labels` is omitted, `LabelAnnotator` uses class names first, then class IDs, then detection indices.
+
+### Can I use supervision with Hugging Face models?
+
+Yes. `sv.Detections.from_transformers()` accepts supported Hugging Face object detection and segmentation outputs. Vision-language model outputs are handled through `sv.Detections.from_vlm(...)`, for example with `sv.VLM.FLORENCE_2` or `sv.VLM.PALIGEMMA`.

+# Detect Small Objects
+
+This guide shows how to detect small objects with the [Inference](https://github.com/roboflow/inference), [Ultralytics](https://github.com/ultralytics/ultralytics) or [Transformers](https://github.com/huggingface/transformers) packages using [`InferenceSlicer`](https://supervision.roboflow.com/latest/detection/tools/inference_slicer/#supervision.detection.tools.inference_slicer.InferenceSlicer).

+## Baseline Detection
+
+Small object detection in high-resolution images presents challenges due to the objects' size relative to the image resolution.
+
+Running a standard detection model on the full image establishes a baseline for comparison. Load your chosen model, pass the image through it, and convert the results into a `Detections` object. This baseline reveals how many small objects the model misses at native resolution, motivating the sliced inference approach shown later.

+
+## Frequently Asked Questions
+
+### How do I detect small objects with supervision?
+
+Use `sv.InferenceSlicer` to split a high-resolution image into overlapping tiles, run detection on each tile, and merge results with non-maximum suppression. This dramatically improves recall for tiny targets.
+
+### What overlap should I use between tiles?
+
+`InferenceSlicer` takes overlap in pixels via `overlap_wh`, not as a percentage. The default is `100` pixels in both directions. Increase `overlap_wh` when objects are close to the tile size or often appear on tile boundaries, and decrease it when speed is more important.
+
+### Can I use InferenceSlicer with any detection model?
+
+Yes. Wrap any model or converter path that can produce `sv.Detections` in a callback, pass that callback to `sv.InferenceSlicer(callback=...)`, and then call the slicer with your image.

+# Filter Detections
+
+The advanced filtering capabilities of the `Detections` class offer users a versatile and efficient way to narrow down and refine object detections. This section outlines various filtering methods, including filtering by specific class or a set of classes, confidence, object area, bounding box area, relative area, box dimensions, and designated zones. Each method is demonstrated with concise code examples to provide users with a clear understanding of how to implement the filters in their applications.

+
+### by area
+
+Allows you to select detections based on their size. We define the area as the number of pixels occupied by the detection in the image. In the example below, we have sifted out the detections that are too small.
+
+=== "After"
+
+    ```python
+    import supervision as sv
+
+    detections = sv.Detections(...)
+    detections = detections[detections.area > 1000]

+
+    </div>
+
+### by relative area
+
+Allows you to select detections based on their size in relation to the size of whole image. Sometimes the concept of detection size changes depending on the image. Detection occupying 10000 square px can be large on a 1280x720 image but small on a 3840x2160 image. In such cases, we can filter out detections based on the percentage of the image area occupied by them. In the example below, we remove too large detections.
+
+=== "After"
+
+    ```python
+    import supervision as sv
+
+    image = ...
+    height, width, channels = image.shape
+    image_area = height * width
+
+    detections = sv.Detections(...)

+
+    </div>
+
+### by box dimensions
+
+Allows you to select detections based on their dimensions. The size of the bounding box, as well as its coordinates, can be criteria for rejecting detection. Implementing such filtering requires a bit of custom code but is relatively simple and fast.
+
+=== "After"
+
+    ```python
+    import supervision as sv
+
+    detections = sv.Detections(...)
+    w = detections.xyxy[:, 2] - detections.xyxy[:, 0]
+    h = detections.xyxy[:, 3] - detections.xyxy[:, 1]

+
+    </div>
+
+### by `PolygonZone`
+
+Allows you to use `Detections` in combination with `PolygonZone` to weed out bounding boxes that are in and out of the zone. In the example below you can see how to filter out all detections located in the lower part of the image.
+
+=== "After"
+
+    ```python
+    import supervision as sv
+
+    zone = sv.PolygonZone(...)
+    detections = sv.Detections(...)
+    mask = zone.trigger(detections=detections)

+
+    </div>
+
+### by mixed conditions
+
+`Detections`' greatest strength, however, is that you can build arbitrarily complex logical conditions by simply combining separate conditions using `&` or `|`.
+
+=== "After"
+
+    ```python
+    import supervision as sv
+
+    zone = sv.PolygonZone(...)
+    detections = sv.Detections(...)

+
+## Frequently Asked Questions
+
+### How do I filter detections by class in supervision?
+
+Use NumPy-style boolean indexing: `detections[detections.class_id == 0]` for class 0. Combine with `&` or `|` for multiple conditions.
+
+### How do I filter by confidence threshold?
+
+`detections[detections.confidence > 0.5]` returns only detections above the threshold. Chain with class filters for precise results.
+
+### How do I filter by bounding box area?
+
+`detections[detections.area > 1000]` filters by pixel area. If masks are present, `detections.area` uses mask area; otherwise it uses bounding box area from `xyxy`. Use `detections.box_area` when you specifically need bounding box area.
+
+### Can I filter by box aspect ratio or dimensions?
+
+Yes. Use `detections.box_aspect_ratio` for aspect ratio filtering. If you need explicit box dimensions, compute them from `detections.xyxy` as `width = detections.xyxy[:, 2] - detections.xyxy[:, 0]` and `height = detections.xyxy[:, 3] - detections.xyxy[:, 1]`.
+
+### How do I remove duplicate detections (NMS) from my results?
+
+Use `detections.with_nms(threshold=0.5)` — it applies non-maximum suppression on the `xyxy` boxes.

+
+With Supervision, you can load and manipulate classification, object detection, and segmentation datasets. This tutorial will walk you through how to load, split, merge, visualize, and augment datasets in Supervision.
+
+## Download Dataset
+
+In this tutorial, we will use a dataset from [Roboflow Universe](https://universe.roboflow.com/), a public repository of thousands of computer vision datasets. If you already have your dataset in [COCO](https://roboflow.com/formats/coco-json), [YOLO](https://roboflow.com/formats/yolov8-pytorch-txt), [Pascal VOC](https://roboflow.com/formats/pascal-voc-xml), [CreateML](https://roboflow.com/formats/createml-json), or [LabelMe](https://roboflow.com/formats/labelme-json) format, you can skip this section.
+
+```bash
+pip install roboflow
+```
+
+Next, log into your Roboflow account and download the dataset of your choice. The following snippets show common COCO, YOLO, Pascal VOC, and CreateML exports; LabelMe datasets can also be loaded directly from per-image JSON files in the next section. You can customize the code with your workspace ID, project ID, and version number.
+
+=== "COCO"
+
+    ```python
+    import roboflow
+
+    roboflow.login()
+
+    rf = roboflow.Roboflow()
+    project = rf.workspace("<WORKSPACE_ID>").project("<PROJECT_ID>")
+    dataset = project.version("<PROJECT_VERSION>").download("coco")
+    ```
+
+=== "YOLO"
+
+    ```python
+    import roboflow
+
+    roboflow.login()
+
+    rf = roboflow.Roboflow()

+
+## Load Dataset
+
+The Supervision library provides convenient functions to load datasets in various formats. If your dataset is already split into train, test, and valid subsets, you can load each of those as separate [`sv.DetectionDataset`](https://supervision.roboflow.com/latest/datasets/core/#supervision.dataset.core.DetectionDataset) instances.
+
+=== "COCO"
+
+    We can do so using the [`sv.DetectionDataset.from_coco`](https://supervision.roboflow.com/latest/datasets/core/#supervision.dataset.core.DetectionDataset.from_coco) to load annotations in [COCO](https://roboflow.com/formats/coco-json) format.
+
+    ```python
+    import supervision as sv
+
+    ds_train = sv.DetectionDataset.from_coco(
+        images_directory_path=f"{dataset.location}/train",
+        annotations_path=f"{dataset.location}/train/_annotations.coco.json",

+    # 800, 100, 100
+    ```
+
+=== "Pascal VOC"
+
+    We can do so using the [`sv.DetectionDataset.from_pascal_voc`](https://supervision.roboflow.com/latest/datasets/core/#supervision.dataset.core.DetectionDataset.from_pascal_voc) to load annotations in [Pascal VOC](https://roboflow.com/formats/pascal-voc-xml) format.
+
+    ```python

+        annotations_path=f"{dataset.location}/test/_annotations.createml.json",
+    )
+
+    ds_train.classes
+    # ['person', 'bicycle', 'car', ...]
+
+    len(ds_train), len(ds_valid), len(ds_test)
+    # 800, 100, 100
+    ```
+
+=== "LabelMe"
+
+    We can do so using the [`sv.DetectionDataset.from_labelme`](https://supervision.roboflow.com/latest/datasets/core/#supervision.dataset.core.DetectionDataset.from_labelme) to load annotations in [LabelMe](https://roboflow.com/formats/labelme-json) format. LabelMe `rectangle` shapes are loaded as bounding boxes and `polygon` shapes are loaded as masks with bounding boxes.
+
+    ```python
+    import supervision as sv
+
+    ds_train = sv.DetectionDataset.from_labelme(
+        images_directory_path="<TRAIN_IMAGES_DIRECTORY_PATH>",
+        annotations_directory_path="<TRAIN_ANNOTATIONS_DIRECTORY_PATH>",
+    )
+    ds_valid = sv.DetectionDataset.from_labelme(
+        images_directory_path="<VALID_IMAGES_DIRECTORY_PATH>",
+        annotations_directory_path="<VALID_ANNOTATIONS_DIRECTORY_PATH>",
+    )
+    ds_test = sv.DetectionDataset.from_labelme(
+        images_directory_path="<TEST_IMAGES_DIRECTORY_PATH>",
+        annotations_directory_path="<TEST_ANNOTATIONS_DIRECTORY_PATH>",
+    )
+
+    ds_train.classes
+    # ['person', 'bicycle', 'car', ...]
+
+    len(ds_train), len(ds_valid), len(ds_test)
+    # 800, 100, 100
+    ```
+
+## Split Dataset
+
+If your dataset is not already split into train, test, and valid subsets, you can easily do so using the [`sv.DetectionDataset.split`](https://supervision.roboflow.com/latest/datasets/core/#supervision.dataset.core.DetectionDataset.split) method. We can split it as follows, ensuring a random shuffle of the data.
+
+```python
+import supervision as sv
+
+ds = sv.DetectionDataset(...)
+
+len(ds)
+# 1000
+
+ds_train, ds = ds.split(split_ratio=0.8, shuffle=True)
+ds_valid, ds_test = ds.split(split_ratio=0.5, shuffle=True)
+
+len(ds_train), len(ds_valid), len(ds_test)
+# 800, 100, 100
+```
+
+## Merge Dataset
+
+If you have multiple datasets that you would like to merge, you can do so using the [`sv.DetectionDataset.merge`](https://supervision.roboflow.com/latest/datasets/core/#supervision.dataset.core.DetectionDataset.merge) method.

+
+## Iterate over Dataset
+
+There are two ways to loop over a `sv.DetectionDataset`: using a direct [for loop](https://supervision.roboflow.com/latest/datasets/core/#supervision.dataset.core.DetectionDataset.__iter__) called on the `sv.DetectionDataset` instance or loading `sv.DetectionDataset` entries [by index](https://supervision.roboflow.com/latest/datasets/core/#supervision.dataset.core.DetectionDataset.__getitem__).
+
+```python
+import supervision as sv
+
+ds = sv.DetectionDataset(...)
+
+# Option 1
+for image_path, image, annotations in ds:
+    ...  # Process each image and its annotations
+
+# Option 2
+for idx in range(len(ds)):
+    image_path, image, annotations = ds[idx]
+    ...  # Process the image and annotations at index `idx`
+```
+
+## Visualize Dataset
+
+The Supervision library provides tools for easily visualizing your detection dataset. You can create a grid of annotated images to quickly inspect your data and labels. First, initialize the [`sv.BoxAnnotator`](https://supervision.roboflow.com/latest/detection/annotators/#supervision.annotators.core.BoxAnnotator) and [`sv.LabelAnnotator`](https://supervision.roboflow.com/latest/detection/annotators/#supervision.annotators.core.LabelAnnotator). Then, iterate through a subset of the dataset (e.g., the first 25 images), drawing bounding boxes and class labels on each image. Finally, combine the annotated images into a grid for display.
+
+```python
+import supervision as sv
+
+ds = sv.DetectionDataset(...)
+
+box_annotator = sv.BoxAnnotator()
+label_annotator = sv.LabelAnnotator()
+
+annotated_images = []
+for i in range(16):
+    _, image, annotations = ds[i]
+
+    labels = [ds.classes[class_id] for class_id in annotations.class_id]
+
+    annotated_image = image.copy()
+    annotated_image = box_annotator.annotate(annotated_image, annotations)
+    annotated_image = label_annotator.annotate(annotated_image, annotations, labels)
+    annotated_images.append(annotated_image)
+
+sv.plot_images_grid(
+    annotated_images,
+    grid_size=(4, 4),
+)
+```

+
+## Save Dataset
+
+=== "COCO"
+
+    We can do so using the [`sv.DetectionDataset.as_coco`](https://supervision.roboflow.com/datasets/#supervision.dataset.core.DetectionDataset.as_coco) method to save annotations in [COCO](https://roboflow.com/formats/coco-json) format.
+
+    ```python
+    import supervision as sv
+
+    ds = sv.DetectionDataset(...)
+
+    ds.as_coco(
+        images_directory_path="<IMAGE_DIRECTORY_PATH>",
+        annotations_path="<ANNOTATIONS_PATH>",
+    )
+    ```
+
+=== "YOLO"
+
+    We can do so using the [`sv.DetectionDataset.as_yolo`](https://supervision.roboflow.com/datasets/#supervision.dataset.core.DetectionDataset.as_yolo) method to save annotations in [YOLO](https://roboflow.com/formats/yolov8-pytorch-txt) format.
+
+    ```python
+    import supervision as sv
+
+    ds = sv.DetectionDataset(...)
+
+    ds.as_yolo(
+        images_directory_path="<IMAGE_DIRECTORY_PATH>",
+        annotations_directory_path="<ANNOTATIONS_DIRECTORY_PATH>",
+        data_yaml_path="<DATA_YAML_PATH>",
+    )
+    ```
+
+=== "Pascal VOC"
+
+    We can do so using the [`sv.DetectionDataset.as_pascal_voc`](https://supervision.roboflow.com/datasets/#supervision.dataset.core.DetectionDataset.as_pascal_voc) method to save annotations in [Pascal VOC](https://roboflow.com/formats/pascal-voc-xml) format.
+
+    ```python
+    import supervision as sv
+
+    ds = sv.DetectionDataset(...)
+
+    ds.as_pascal_voc(
+        images_directory_path="<IMAGE_DIRECTORY_PATH>",
+        annotations_directory_path="<ANNOTATIONS_DIRECTORY_PATH>",
+    )
+    ```
+
+=== "CreateML"
+
+    We can do so using the [`sv.DetectionDataset.as_createml`](https://supervision.roboflow.com/latest/datasets/core/#supervision.dataset.core.DetectionDataset.as_createml) method to save annotations in [CreateML](https://roboflow.com/formats/createml-json) format.
+
+    ```python
+    import supervision as sv
+
+    ds = sv.DetectionDataset(...)
+
+    ds.as_createml(
+        images_directory_path="<IMAGE_DIRECTORY_PATH>",
+        annotations_path="<ANNOTATIONS_PATH>",
+    )
+    ```
+
+=== "LabelMe"
+
+    We can do so using the [`sv.DetectionDataset.as_labelme`](https://supervision.roboflow.com/latest/datasets/core/#supervision.dataset.core.DetectionDataset.as_labelme) method to save annotations in [LabelMe](https://roboflow.com/formats/labelme-json) format. Detections with masks are exported as `polygon` shapes; box-only detections are exported as `rectangle` shapes.
+
+    ```python
+    import supervision as sv
+
+    ds = sv.DetectionDataset(...)
+
+    ds.as_labelme(
+        images_directory_path="<IMAGE_DIRECTORY_PATH>",
+        annotations_directory_path="<ANNOTATIONS_DIRECTORY_PATH>",
+    )
+    ```
+
+## Augment Dataset
+
+In this section, we'll explore using Supervision in combination with Albumentations to augment our dataset. Data augmentation is a common technique in computer vision to increase the size and diversity of training datasets, leading to improved model performance and generalization.
+
+```bash
+pip install albumentations
+```
+
+Albumentations provides a flexible and powerful API for image augmentation. The core of the library is the [`Compose`](https://albumentations.ai/docs/api-reference/albumentations/core/composition/#Compose) class, which allows you to chain multiple image transformations together. Each transformation is defined using a dedicated class, such as [`HorizontalFlip`](https://albumentations.ai/docs/api-reference/albumentations/augmentations/geometric/flip/#HorizontalFlip), [`RandomBrightnessContrast`](https://albumentations.ai/docs/api-reference/albumentations/augmentations/pixel/transforms/#RandomBrightnessContrast), or [`Perspective`](https://albumentations.ai/docs/api-reference/albumentations/augmentations/geometric/transforms/#Perspective).
+
+```python
+import albumentations as A
+
+augmentation = A.Compose(
+    transforms=[
+        A.Perspective(p=0.1),
+        A.HorizontalFlip(p=0.5),
+        A.RandomBrightnessContrast(p=0.5),
+    ],
+    bbox_params=A.BboxParams(
+        format="pascal_voc",
+        label_fields=["category"],
+    ),
+)
+```
+
+The key is to set `format='pascal_voc'`, which corresponds to the `[x_min, y_min, x_max, y_max]` bounding box format used in Supervision.
+
+```python
+import numpy as np
+import supervision as sv
+from dataclasses import replace
+
+ds = sv.DetectionDataset(...)
+
+_, original_image, original_annotations = ds[0]
+
+output = augmentation(
+    image=original_image,
+    bboxes=original_annotations.xyxy,
+    category=original_annotations.class_id,
+)
+
+augmented_image = output["image"]
+augmented_annotations = replace(
+    original_annotations,
+    xyxy=np.array(output["bboxes"]),
+    class_id=np.array(output["category"]),
+)
+```

+
+## Frequently Asked Questions
+
+### What dataset formats does supervision support?
+
+For detection datasets, supervision supports YOLO, COCO JSON, Pascal VOC, CreateML, and LabelMe. Use `DetectionDataset.from_yolo()`, `from_coco()`, `from_pascal_voc()`, `from_createml()`, or `from_labelme()` to load, and `as_yolo()`, `as_coco()`, `as_pascal_voc()`, `as_createml()`, or `as_labelme()` to save. Classification datasets use `ClassificationDataset.from_folder_structure()` and `as_folder_structure()`.
+
+### Can I split a dataset into train/val/test sets?
+
+`DetectionDataset.split(split_ratio=0.8)` returns exactly two datasets: train (80%) and test (20%). If you need a validation set, split one of those subsets in a separate step.
+
+### Can I merge two datasets together?
+
+Yes. `DetectionDataset.merge([dataset_a, dataset_b])` combines multiple datasets into one. Useful for combining datasets from different sources.
+
+### What augmentations are available?
+
+Common augmentations such as flip, rotate, translate, scale, crop, color jitter, and Gaussian blur can be applied using an external library like Albumentations, as shown in the augmentation example above. Supervision does not provide an `sv.Augmenter` pipeline.

+# Save Detections
+
+Supervision enables an easy way to save detections in .CSV and .JSON files for offline processing. This guide demonstrates how to perform video inference using the [Inference](https://github.com/roboflow/inference), [Ultralytics](https://github.com/ultralytics/ultralytics) or [Transformers](https://github.com/huggingface/transformers) packages and save their results with [`sv.CSVSink`](https://supervision.roboflow.com/latest/detection/tools/save_detections/#supervision.detection.tools.csv_sink.CSVSink) and [`sv.JSONSink`](https://supervision.roboflow.com/latest/detection/tools/save_detections/#supervision.detection.tools.json_sink.JSONSink).
+
+## Run Detection
+
+First, you'll need to obtain predictions from your object detection or segmentation model. You can learn more on this topic in our [How to Detect and Annotate](https://supervision.roboflow.com/latest/how_to/detect_and_annotate/) guide.
+
+To generate predictions for saving, initialize your model and iterate over video frames using `sv.get_video_frames_generator`. Each frame is passed to the model, and the raw output is converted into a `sv.Detections` object. This detection loop forms the foundation for both CSV and JSON export workflows shown below.
+
+=== "Inference"
+
+    ```python
+    import supervision as sv
+    from inference import get_model
+
+    model = get_model(model_id="yolov8n-640")
+    frames_generator = sv.get_video_frames_generator("<SOURCE_VIDEO_PATH>")
+
+    for frame in frames_generator:
+        results = model.infer(image)[0]
+        detections = sv.Detections.from_inference(results)
+    ```
+
+=== "Ultralytics"
+
+    ```python
+    import supervision as sv
+    from ultralytics import YOLO
+
+    model = YOLO("yolov8n.pt")
+    frames_generator = sv.get_video_frames_generator("<SOURCE_VIDEO_PATH>")
+
+    for frame in frames_generator:
+        results = model(frame)[0]
+        detections = sv.Detections.from_ultralytics(results)
+    ```
+
+=== "Transformers"
+
+    ```python
+    import torch
+    import supervision as sv
+    from transformers import DetrImageProcessor, DetrForObjectDetection
+
+    processor = DetrImageProcessor.from_pretrained("facebook/detr-resnet-50")
+    model = DetrForObjectDetection.from_pretrained("facebook/detr-resnet-50")
+    frames_generator = sv.get_video_frames_generator("<SOURCE_VIDEO_PATH>")
+
+    for frame in frames_generator:
+        frame = sv.cv2_to_pillow(frame)
+        inputs = processor(images=frame, return_tensors="pt")
+
+        with torch.no_grad():
+            outputs = model(**inputs)
+
+        width, height = frame.size
+        target_size = torch.tensor([[height, width]])
+        results = processor.post_process_object_detection(
+            outputs=outputs, target_sizes=target_size
+        )[0]
+        detections = sv.Detections.from_transformers(results)
+    ```
+
+## Save Detections as CSV
+
+To save detections to a `.CSV` file, open our [`sv.CSVSink`](https://supervision.roboflow.com/latest/detection/tools/save_detections/#supervision.detection.tools.csv_sink.CSVSink) and then pass the [`sv.Detections`](https://supervision.roboflow.com/latest/detection/core/#supervision.detection.core.Detections) object resulting from the inference to it. Its fields are parsed and saved on disk.

+## Custom Fields
+
+Besides regular fields in [`sv.Detections`](https://supervision.roboflow.com/latest/detection/core/#supervision.detection.core.Detections), [`sv.CSVSink`](https://supervision.roboflow.com/latest/detection/tools/save_detections/#supervision.detection.tools.csv_sink.CSVSink) also allows you to add custom information to each row, which can be passed via the `custom_data` dictionary. Let's utilize this feature to save information about the frame index from which the detections originate.

+
+## Frequently Asked Questions
+
+### How do I save detections to CSV with supervision?
+
+Open `sv.CSVSink("output.csv")` as a context manager and call `sink.append(detections)` for each frame. The CSV includes box coordinates, confidence, class ID, tracker ID, and any fields stored in `detections.data`.
+
+### Can I save detections to JSON instead?
+
+Yes. Open `sv.JSONSink("output.json")` as a context manager and call `sink.append(detections)` for each frame. The file is written as a JSON array when the context exits.
+
+### Can I add custom fields to the saved output?
+
+Yes. Pass a dict as the second argument: `sink.append(detections, {"frame_index": 5})` — the keys become extra columns in the CSV or extra fields in the JSON.
+
+### Can I save only specific classes or confidence levels?
+
+Filter the `Detections` object before saving: `sink.append(detections[detections.confidence > 0.7])`.

+# Track Objects
+
+Leverage Supervision's advanced capabilities for enhancing your video analysis by seamlessly [tracking](https://supervision.roboflow.com/latest/trackers/) objects recognized by a multitude of object detection, segmentation and keypoint models. This comprehensive guide will take you through the steps to perform inference using the YOLOv8 model via either the [Inference](https://github.com/roboflow/inference) or [Ultralytics](https://github.com/ultralytics/ultralytics) packages. Following this, you'll discover how to track these objects efficiently and annotate your video content for a deeper analysis.
+
+## Object Detection & Segmentation
+
+To make it easier for you to follow our tutorial download the video we will use as an example. You can do this using the [`supervision.assets`](https://supervision.roboflow.com/latest/assets/) module included in the base package.
+
+This section demonstrates how to detect and segment objects in video frames using YOLOv8 with either the Inference or Ultralytics package. You will download a sample video, define a per-frame callback function that runs model prediction, and process the entire video to produce an annotated output file.
+
+```python
+from supervision.assets import download_assets, VideoAssets
+
+download_assets(VideoAssets.PEOPLE_WALKING)
+```
+
+<video controls>
+    <source src="https://media.roboflow.com/supervision/video-examples/people-walking.mp4" type="video/mp4">
+</video>
+
+### Run Inference
+
+First, you'll need to obtain predictions from your object detection or segmentation model. In this tutorial, we are using the YOLOv8 model as an example. However, Supervision is versatile and compatible with various models. Check this [link](https://supervision.roboflow.com/latest/how_to/detect_and_annotate/#load-predictions-into-supervision) for guidance on how to plug in other models.
+
+We will define a `callback` function, which will process each frame of the video by obtaining model predictions and then annotating the frame based on these predictions. This `callback` function will be essential in the subsequent steps of the tutorial, as it will be modified to include tracking, labeling, and trace annotations.
+
+!!! tip
+
+    Both object detection and segmentation models are supported. Try it with `yolov8n.pt` or `yolov8n-640-seg`!

+
+### Tracking
+
+After running inference and obtaining predictions, the next step is to track the detected objects throughout the video. Utilizing Supervision’s [`sv.ByteTrack`](https://supervision.roboflow.com/latest/trackers/#supervision.tracker.byte_tracker.core.ByteTrack) functionality, each detected object is assigned a unique tracker ID, enabling the continuous following of the object's motion path across different frames.
+
+!!! warning "Deprecated tracker wrapper"
+
+    `sv.ByteTrack` is deprecated in favor of `ByteTrackTracker` from the external `trackers` package. The external tracker uses `update()` instead of `update_with_detections()`.
+
+=== "Ultralytics"

+    )
+    ```
+
+### Annotate Video with Tracking IDs
+
+Annotating the video with tracking IDs helps in distinguishing and following each object distinctly. With the [`sv.LabelAnnotator`](https://supervision.roboflow.com/latest/detection/annotators/#supervision.annotators.core.LabelAnnotator) in Supervision, we can overlay the tracker IDs and class labels on the detected objects, offering a clear visual representation of each object's class and unique identifier.

+### Annotate Video with Traces
+
+Adding traces to the video involves overlaying the historical paths of the detected objects. This feature, powered by the [`sv.TraceAnnotator`](https://supervision.roboflow.com/latest/detection/annotators/#supervision.annotators.core.TraceAnnotator), allows for visualizing the trajectories of objects, helping in understanding the movement patterns and interactions between objects in the video.

+## Keypoints
+
+Models aren't limited to object detection and segmentation. Keypoint detection allows for detailed analysis of body joints and connections, especially valuable for applications like human pose estimation. This section introduces keypoint tracking. We'll walk through the steps of annotating keypoints, converting them into bounding box detections compatible with `ByteTrack`, and applying detection smoothing for enhanced stability.
+
+To make it easier for you to follow our tutorial, let's download the video we will use as an example. You can do this using the [`supervision.assets`](https://supervision.roboflow.com/latest/assets/) module included in the base package.
+
+```python
+from supervision.assets import download_assets, VideoAssets
+
+download_assets(VideoAssets.SKIING)
+```

+
+### Keypoint Detection
+
+First, you'll need to obtain predictions from your keypoint detection model. In this tutorial, we are using the YOLOv8 model as an example. However, Supervision is versatile and compatible with various models. Check this [link](https://supervision.roboflow.com/latest/keypoint/core/) for guidance on how to plug in other models.
+
+We will define a `callback` function, which will process each frame of the video by obtaining model predictions and then annotating the frame based on these predictions.
+
+Let's immediately visualize the results with our [`EdgeAnnotator`](https://supervision.roboflow.com/latest/keypoint/annotators/#supervision.key_points.annotators.EdgeAnnotator) and [`VertexAnnotator`](https://supervision.roboflow.com/latest/keypoint/annotators/#supervision.key_points.annotators.VertexAnnotator).

+
+### Convert to Detections
+
+Keypoint tracking is currently supported via the conversion of `KeyPoints` to `Detections`. This is achieved with the [`KeyPoints.as_detections()`](https://supervision.roboflow.com/latest/keypoint/core/#supervision.key_points.core.KeyPoints.as_detections) function.
+
+Let's convert to detections and visualize the results with our [`BoxAnnotator`](https://supervision.roboflow.com/latest/detection/annotators/#supervision.annotators.core.BoxAnnotator).
+
+!!! tip
+
+    You may use the `selected_keypoint_indices` argument to specify a subset of keypoints to convert. This is useful when some keypoints could be occluded. For example: a person might swing their arm, causing the elbow to be occluded by the torso sometimes.

+### Keypoint Tracking
+
+Now that we have a `Detections` object, we can track it throughout the video. Utilizing Supervision's [`sv.ByteTrack`](https://supervision.roboflow.com/latest/trackers/#supervision.tracker.byte_tracker.core.ByteTrack) functionality, each detected object is assigned a unique tracker ID, enabling the continuous following of the object's motion path across different frames. We shall visualize the result with `TraceAnnotator`.

+
+### Bonus: Smoothing
+
+We could stop here as we have successfully tracked the object detected by the keypoint model. However, we can further enhance the stability of the boxes by applying [`DetectionsSmoother`](https://supervision.roboflow.com/latest/detection/tools/smoother/). This tool helps in stabilizing the boxes by smoothing the bounding box coordinates across frames. It is very simple to use:

+
+This structured walkthrough should give a detailed pathway to annotate videos effectively using Supervision’s various functionalities, including object tracking and trace annotations.
+
+## Frequently Asked Questions
+
+### How do I track objects across video frames with supervision?
+
+Pass `Detections` to `sv.ByteTrack.update_with_detections()` on each frame. The tracker assigns persistent IDs. Combine with `sv.TraceAnnotator` to visualize trajectories. `sv.ByteTrack` is deprecated in favor of `ByteTrackTracker` from the `trackers` package, where the update method is named `update()`.
+
+### What should I know about ByteTrack?
+
+ByteTrack uses low-confidence detections during association, which can improve continuity during missed or weak detections. Supervision's built-in `ByteTrack` wrapper is deprecated in favor of the external `trackers` package.
+
+### Can I track instances instead of bounding boxes?
+
+Yes. ByteTrack tracks bounding boxes. For instance masks, use `sv.MaskAnnotator` with the tracker IDs to color-code each tracked object consistently.
+
+### Does ByteTrack work with any detection model?
+
+Yes. ByteTrack is model-agnostic - it accepts any `Detections` object with bounding boxes, regardless of the supported converter or model output that produced it.

+
+# Use Compact Masks for Memory-Efficient Segmentation
+
+[CompactMask][supervision.detection.compact_mask.CompactMask] stores each instance mask as a run-length encoding of its bounding-box **crop** rather than a full `(H, W)` boolean frame. For high-resolution images with many sparse masks this can reduce memory from tens of gigabytes to tens of megabytes, and eliminates full-frame decode work in annotators that only need the cropped region.
+
+!!! Note
+
+    `sv.mask_to_xyxy` keeps supervision's inclusive max-coordinate convention for compatibility with `CompactMask` and current box-based adapters. Use `sv.mask_to_roi` when you need exclusive slice bounds for NumPy indexing or crop extraction.
+
+This guide covers the four main integration points:
+
+1. [Ingesting COCO RLE payloads directly as CompactMask](#ingest-coco-rle-payloads)
+2. [Parsing Roboflow Inference results without a dense stack](#parse-inference-results)
+3. [Skipping mask materialisation for box/label annotators](#skip-unnecessary-materialisation)
+4. [Merging mixed dense and compact detections](#merge-mixed-detections)
+
+---
+
+## Ingest COCO RLE Payloads
+
+If your model or API returns masks in the COCO RLE format (`{"size": [H, W], "counts": "..."}`) you can convert them directly to `CompactMask` without allocating an `(N, H, W)` boolean array:
+
+```python
+import numpy as np
+import supervision as sv
+from supervision.detection.compact_mask import CompactMask
+
+# Example: two COCO RLE masks for a 720×1280 frame.
+# Replace the counts strings with actual compressed RLE payloads from your
+# model or API — e.g., from pycocotools mask.encode() or an Inference response.
+rles = [
+    {"size": [720, 1280], "counts": "YOUR_RLE_COUNTS_STRING_HERE"},
+    {"size": [720, 1280], "counts": "YOUR_RLE_COUNTS_STRING_HERE"},
+]
+xyxy = np.array(
+    [
+        [100.0, 50.0, 400.0, 300.0],
+        [500.0, 200.0, 900.0, 600.0],
+    ]
+)
+
+compact = CompactMask.from_coco_rle(rles, xyxy, image_shape=(720, 1280))
+
+detections = sv.Detections(
+    xyxy=xyxy,
+    mask=compact,
+    class_id=np.array([0, 1]),
+)
+```
+
+`from_coco_rle` uses run-length arithmetic scoped to each bounding box so no dense pixel array is ever created. Uncompressed integer count lists are also accepted in place of compressed strings.
+
+---
+
+## Parse Inference Results
+
+`Detections.from_inference` accepts a `compact_masks=True` flag that routes the Roboflow RLE payload through `CompactMask.from_coco_rle` instead of decoding to a dense stack:
+
+```python
+import supervision as sv
+
+# result: a Roboflow Inference v2 response dict with instance masks.
+detections = sv.Detections.from_inference(result, compact_masks=True)
+
+from supervision.detection.compact_mask import CompactMask
+
+assert isinstance(detections.mask, CompactMask)
+```
+
+!!! Warning
+
+    `compact_masks=True` crops each mask to its detector bounding box. Pixels outside the box are silently dropped. For masks that extend meaningfully beyond the reported bounding box, use the default `compact_masks=False` (dense decode) to preserve all pixels.
+
+To convert an existing dense-mask `Detections` to compact at any point:
+
+```python
+detections_compact = detections.to_compact_masks()
+```
+
+---
+
+## Skip Unnecessary Materialisation
+
+Annotators that do not draw masks (box, label, circle, ellipse, trace, keypoint) expose `requires_mask = False`. Integrations can branch on this flag to avoid decoding compact or RLE masks before annotation:
+
+```python
+import supervision as sv
+
+annotators = [
+    sv.BoxAnnotator(),
+    sv.LabelAnnotator(),
+    sv.MaskAnnotator(),  # requires_mask = True
+]
+
+for ann in annotators:
+    if ann.requires_mask:
+        # Annotator reads mask pixels — CompactMask decodes lazily per crop.
+        scene = ann.annotate(scene, detections)
+    else:
+        # Annotator ignores masks — strip mask field to eliminate any decode cost.
+        det_no_mask = sv.Detections(
+            xyxy=detections.xyxy,
+            confidence=detections.confidence,
+            class_id=detections.class_id,
+        )
+        scene = ann.annotate(scene, det_no_mask)
+```
+
+Annotators that set `requires_mask = True`: [MaskAnnotator][supervision.annotators.core.MaskAnnotator], [PolygonAnnotator][supervision.annotators.core.PolygonAnnotator], [HaloAnnotator][supervision.annotators.core.HaloAnnotator].
+
+All others default to `requires_mask = False`.
+
+!!! Note
+
+    `PolygonAnnotator` and `MaskAnnotator` both operate directly on `CompactMask` without materialising the full `(N, H, W)` frame — passing compact detections to them is already efficient.
+
+---
+
+## Merge Mixed Detections
+
+When merging `Detections` objects that mix dense `ndarray` masks and `CompactMask` instances, `Detections.merge` converts dense inputs to `CompactMask` automatically. No full `(N, H, W)` stack is allocated:
+
+```python
+import numpy as np
+import supervision as sv
+from supervision.detection.compact_mask import CompactMask
+
+H, W = 720, 1280
+
+# Compact detections from an RLE-based source.
+# Replace the counts string with a real compressed RLE payload from your model or API.
+rles = [{"size": [H, W], "counts": "YOUR_RLE_COUNTS_STRING_HERE"}]
+xyxy_a = np.array([[100.0, 50.0, 400.0, 300.0]])
+cm = CompactMask.from_coco_rle(rles, xyxy_a, image_shape=(H, W))
+det_a = sv.Detections(xyxy=xyxy_a, mask=cm, class_id=np.array([0]))
+
+# Dense detections from a different source.
+masks_b = np.zeros((1, H, W), dtype=bool)

+| ------------------------------------- | ------------------------------- |
+| All `CompactMask`                     | `CompactMask`                   |
+| Mixed `CompactMask` + dense `ndarray` | `CompactMask`                   |
+| All dense `ndarray`                   | `ndarray` (backward compatible) |
+
+All `CompactMask` inputs must share the same `image_shape`; mismatches raise `ValueError`.
+

+
+## Performance Notes
+
+These estimates apply to the **parsing and annotation stage**, not end-to-end pipeline FPS. Model inference typically dominates total runtime.
+
+| Optimisation                 | Realistic gain             | Applies when                                                  |
+| ---------------------------- | -------------------------- | ------------------------------------------------------------- |
+| `from_coco_rle` ingestion    | 25–60% faster parse        | Full-frame COCO RLE payload; current dense decode path        |
+| `MaskAnnotator` ROI blending | 10–35% faster annotation   | Many small, sparse masks on high-res frames                   |
+| `PolygonAnnotator` crop path | 15–45% faster polygon draw | Many compact masks; full-frame materialise was the bottleneck |
+| Mixed-mask merge             | 5–20% faster merge         | Mix of compact and dense sources (e.g. multi-camera stitch)   |
+
+Upper-end gains assume: ≥1080p frames, tens to hundreds of instances, masks covering less than ~20% of total pixels.

+## What is Supervision?
+
+Supervision is an open-source Python library by Roboflow for building computer vision applications. It provides a unified `Detections` object with converters for supported outputs from Ultralytics, Roboflow Inference, Transformers, SAM, Detectron2, MMDetection, YOLO-NAS, PaddleDet, NCNN, Azure AI Vision, and VLM parsers.
+
+With Supervision you can annotate images and video with bounding boxes, masks, and labels; track objects across frames with persistent IDs; count and filter detections inside polygon zones; load and convert datasets between YOLO, COCO, and Pascal VOC formats; and benchmark model performance with mAP and confusion matrices.
+
+Supervision is MIT licensed, has 38,000+ GitHub stars, and over 1 million monthly PyPI downloads. It is developed in public on GitHub for production computer vision workflows.
+
+## 👋 Hello
+
+We write your reusable computer vision tools. Whether you need to load your dataset from your hard drive, draw detections on an image or video, or count how many detections are in a zone. You can count on us!

+> Large-context AI crawler summary for Supervision documentation.
+
+Supervision is an open-source Python library by Roboflow for computer vision workflows. It provides a model-agnostic `Detections` class and composable tools for object detection, instance segmentation, keypoint detection, annotation, tracking, zone counting, dataset conversion, and model evaluation.
+
+Supervision is MIT licensed, published on PyPI, developed on GitHub, and used by researchers and practitioners in production computer vision systems. The library includes converters for supported outputs from Ultralytics, Roboflow Inference, Hugging Face Transformers, SAM, Detectron2, MMDetection, YOLO-NAS, PaddleDet, NCNN, Azure AI Vision, and VLM parsers.

+
+## Core Concepts
+
+### `sv.Detections`
+
+`sv.Detections` is the central data structure in Supervision. It stores bounding boxes, segmentation masks, confidence scores, class IDs, tracker IDs, and arbitrary per-detection metadata in a `data` dictionary. It supports NumPy-style indexing for filtering by confidence, class, area, and spatial constraints.
+
+Most connectors, annotators, trackers, dataset tools, and metrics either accept or return `Detections`, which makes it possible to change the upstream model while keeping downstream processing code stable.
+
+### Model Connectors
+
+Supervision normalizes outputs from multiple computer vision frameworks into the same `Detections` API. Common constructors include:
+
+- `sv.Detections.from_ultralytics(...)`
+- `sv.Detections.from_inference(...)`
+- `sv.Detections.from_transformers(...)`
+- `sv.Detections.from_vlm(...)`
+- `sv.Detections.from_sam(...)`
+- `sv.Detections.from_detectron2(...)`
+- `sv.Detections.from_mmdetection(...)`
+
+### Annotation
+
+Supervision includes annotators for drawing boxes, masks, labels, traces, zones, vertices, edges, and other overlays on images and video frames. Common annotators include:
+
+- `sv.BoxAnnotator`
+- `sv.MaskAnnotator`
+- `sv.LabelAnnotator`
+- `sv.TraceAnnotator`
+- `sv.PolygonZoneAnnotator`
+- `sv.LineZoneAnnotator`
+
+### Tracking
+
+The built-in `sv.ByteTrack` wrapper assigns persistent IDs across video frames through `update_with_detections()`. The docs also note the migration path toward `ByteTrackTracker` from the external `trackers` package. Tracked detections can be passed to label, trace, zone, and line-counting annotators.
+
+### Zones and Counting
+
+`sv.PolygonZone` checks whether detections are inside an arbitrary polygon. `sv.LineZone` counts line crossings and requires `detections.tracker_id` so objects can be matched across frames. These tools are typically used with video callbacks and annotators to build traffic, occupancy, queue, and throughput analytics.
+
+### Datasets
+
+`sv.DetectionDataset` loads, merges, splits, and converts object detection datasets. Supported formats include YOLO, COCO JSON, Pascal VOC, and LabelMe. `sv.ClassificationDataset` supports folder-structured classification datasets.
+
+### Metrics
+
+Supervision includes detection metrics including mean average precision, mean average recall, precision, recall, F1 score, and confusion matrices. The current mAP workflow uses `supervision.metrics.mean_average_precision.MeanAveragePrecision` with `update(...)` and `compute()`.

+## Frequently Asked Questions
+
+### What is Supervision?
+
+Supervision is an open-source Python library by Roboflow for computer vision workflows. It provides a unified `Detections` class with converters for supported detection, segmentation, and VLM outputs.
+
+### Is Supervision tied to one model provider?
+
+No. Supervision is model agnostic. It is designed to normalize model outputs into a common API so downstream annotation, filtering, tracking, metrics, and dataset code can be reused.
+
+### What dataset formats are supported?
+
+For object detection datasets, Supervision supports YOLO, COCO JSON, Pascal VOC, and LabelMe import and export. For classification datasets, it supports folder-structure import and export.
+
+### How do I detect small objects?
+
+Use `sv.InferenceSlicer` to split large images into overlapping tiles, run inference on each tile, and merge the resulting detections with non-maximum suppression or non-maximum merge.
+
+### How do I count objects crossing a line?
+
+Run a tracker first to assign `detections.tracker_id`, then use `sv.LineZone.trigger(detections)` to calculate crossing events. Use `sv.LineZoneAnnotator` for visualization.
+
+### How do I benchmark a model?
+
+Load predictions and ground truth as `Detections`, update a `MeanAveragePrecision` metric object, and call `compute()`. Use `sv.ConfusionMatrix` when class-level confusion analysis is needed.

+## Key APIs
+
+### sv.Detections
+
+Core data structure for bounding boxes, masks, confidence scores, class IDs, tracker IDs, and arbitrary per-detection metadata stored in a `data` dict. The lingua franca of the entire library — every connector, annotator, and tracker accepts or returns `Detections`. Supports NumPy-style boolean indexing for filtering by class, confidence, area, and spatial regions.
+
+### sv.BoxAnnotator, sv.MaskAnnotator, sv.LabelAnnotator
+
+Draw bounding boxes, segmentation masks, and text labels on images. Annotators expose `annotate(scene=..., detections=...)`; pass an input image and a `Detections` object to get the annotated output. `LabelAnnotator` can use explicit `labels` or fall back to `detections["class_name"]`, class IDs, then detection indices. Colors can be assigned by class or manually specified.
+
+### sv.ByteTrack
+
+Object tracker wrapper that assigns persistent IDs across video frames. The built-in `sv.ByteTrack` accepts `Detections` via `update_with_detections()`, but it is deprecated in favor of `ByteTrackTracker` from the external `trackers` package, where the method is named `update()`. Use tracked `Detections` with `sv.TraceAnnotator` to visualize trajectories.
+
+### sv.PolygonZone and sv.LineZone
+
+Zone-based counting. `PolygonZone.trigger(detections)` returns a boolean mask for detections currently inside an arbitrary polygon. `LineZone.trigger(detections)` returns `(crossed_in, crossed_out)` arrays for line crossings and requires `detections.tracker_id` so objects can be matched across frames. Both are commonly paired with zone annotators for visualization.
+
+### sv.DetectionDataset and sv.ClassificationDataset
+
+For detection datasets, load, merge, split, and convert between YOLO, COCO JSON, Pascal VOC, and LabelMe formats. Classification datasets use folder-structure import and export via `ClassificationDataset.from_folder_structure()` and `as_folder_structure()`.
+
+### sv.InferenceSlicer
+
+SAHI-style inference slicing: split high-resolution images into overlapping tiles, run detection on each tile, merge results with non-maximum suppression or non-maximum merge. Configure tile overlap in pixels with `overlap_wh`.
+
+### supervision.metrics.MeanAveragePrecision and sv.ConfusionMatrix
+
+Benchmarking tools. For mAP@0.5:0.95, use `supervision.metrics.MeanAveragePrecision` with `update()` and `compute()` rather than the deprecated top-level `sv.MeanAveragePrecision.from_detections()`. `ConfusionMatrix.from_detections(predictions=predictions, targets=targets, classes=classes)` generates a confusion matrix for detection results.
+
+### sv.CSVSink and sv.JSONSink
+
+Export detection results to structured files. Use `CSVSink` and `JSONSink` as context managers, call `sink.append(detections, custom_data=...)`, and they write one row/object per detection with box coordinates, confidence, class ID, tracker ID, and data fields.

+## FAQ
+
+### What is supervision?
+
+Supervision is an open-source Python library by Roboflow for computer vision workflows. It provides a unified `Detections` class with converters for supported detection, segmentation, and VLM outputs, plus tools for annotation, tracking, zone counting, dataset management, and model benchmarking.
+
+### How do I install supervision?
+
+Install with `pip install supervision`. For optional metric dependencies use `pip install supervision[metrics]`. Sample asset utilities are included in the base package under `supervision.assets`. The current package metadata requires Python 3.10+.
+
+### What can I do with supervision?
+
+Annotate images and video with bounding boxes, masks, and labels; track objects across frames with persistent IDs; count detections inside polygon zones or line crossings; filter and query detection results; load, split, and convert detection datasets between YOLO, COCO, Pascal VOC, and LabelMe formats; manage classification datasets with folder structures; and benchmark model performance with mAP and confusion matrices.
+
+### Is supervision free to use?
+
+Yes. Supervision is free and open-source under the MIT license. Source code is at https://github.com/roboflow/supervision.
+
+### Which object detection models work with supervision?
+
+Supervision is model-agnostic and works with supported outputs from Ultralytics YOLO, Roboflow Inference, Hugging Face Transformers, SAM, Detectron2, MMDetection, YOLO-NAS, PaddleDet, NCNN, Azure AI Vision, and VLM parsers such as Florence-2, PaliGemma, Qwen VL, Gemini, DeepSeek VL 2, and Moondream. Keypoint outputs have separate converters, including MediaPipe.
+
+### How do I benchmark a model with supervision?
+
+Use `supervision.metrics.mean_average_precision.MeanAveragePrecision` for mAP — accumulate predictions and ground truth with `update(...)` then call `compute()`. For confusion matrices, use `sv.ConfusionMatrix.from_detections(predictions=predictions, targets=targets, classes=classes)`. See the Benchmark a Model how-to guide for a complete walkthrough.
+
+### How do I track objects across video frames?
+
+Use a tracker to assign persistent IDs. The built-in `sv.ByteTrack` wrapper accepts `Detections` with `update_with_detections()`, but it is deprecated in favor of `ByteTrackTracker` from the external `trackers` package. Combine tracked detections with `sv.TraceAnnotator` to visualize trajectories.
+
+### What dataset formats does supervision support?
+
+For detection datasets, supervision supports YOLO, COCO JSON, Pascal VOC, and LabelMe. Use `DetectionDataset.from_yolo()`, `from_coco()`, `from_pascal_voc()`, or `from_labelme()` to load, and `as_yolo()`, `as_coco()`, `as_pascal_voc()`, or `as_labelme()` to save. For classification datasets, use `ClassificationDataset.from_folder_structure()` and `as_folder_structure()`.
+
+### How do I count objects in a zone?
+
+Use `sv.PolygonZone` for arbitrary polygon zones. Use `sv.LineZone` for line-crossing counts after assigning tracker IDs, because `LineZone` needs `detections.tracker_id` to match objects across frames.
+
+### How do I detect small objects with supervision?
+
+Use `sv.InferenceSlicer` to split high-resolution images into overlapping tiles, run detection on each tile, and merge results with non-maximum suppression. Configure tile overlap in pixels with `overlap_wh`. See the Detect Small Objects how-to guide.
+
+## Benchmarking
+
+Supervision includes `supervision.metrics.MeanAveragePrecision` and `sv.ConfusionMatrix` for benchmarking object detection models. A curated [Model Leaderboard](https://leaderboard.roboflow.com/) compares YOLOv8, YOLOv11, and other models on standard datasets. The leaderboard repository is open source at https://github.com/roboflow/model-leaderboard.
