## 👋 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! 🤝
|
|
|
|
## 💻 install
|
|
|
|
Pip install the supervision package in a
|
|
[**Python>=3.8**](https://www.python.org/) environment.
|
|
|
|
```bash
|
|
pip install supervision
|
|
```
|
|
|
|
Read more about desktop, headless, and local installation 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/detection/core/#detections) for the most popular libraries like Ultralytics, Transformers, or MMDetection.
|
|
|
|
```python
|
|
>>> import cv2
|
|
>>> import supervision as sv
|
|
>>> from ultralytics import YOLO
|
|
|
|
>>> image = cv2.imread(...)
|
|
>>> model = YOLO('yolov8s.pt')
|
|
>>> result = model(image)[0]
|
|
>>> detections = sv.Detections.from_ultralytics(result)
|
|
|
|
>>> len(detections)
|
|
5
|
|
```
|
|
|
|
### annotators
|
|
|
|
Supervision offers a wide range of highly customizable [annotators](https://supervision.roboflow.com/annotators/), allowing you to compose the perfect visualization for your use case.
|
|
|
|
```python
|
|
>>> import cv2
|
|
>>> import supervision as sv
|
|
|
|
>>> image = cv2.imread(...)
|
|
>>> detections = sv.Detections(...)
|
|
|
|
>>> bounding_box_annotator = sv.BoundingBoxAnnotator()
|
|
>>> annotated_frame = bounding_box_annotator.annotate(
|
|
... scene=image.copy(),
|
|
... detections=detections
|
|
... )
|
|
```
|

|
|
|
|
### datasets
|
|
|
|
Supervision provides a set of [utils](https://supervision.roboflow.com/datasets/) that allow you to load, split, merge, and save datasets in one of the supported formats.
|
|
|
|
```python
|
|
>>> import supervision as sv
|
|
|
|
>>> dataset = sv.DetectionDataset.from_yolo(
|
|
... images_directory_path=...,
|
|
... annotations_directory_path=...,
|
|
... data_yaml_path=...
|
|
... )
|
|
|
|
>>> dataset.classes
|
|
['dog', 'person']
|
|
|
|
>>> len(dataset)
|
|
1000
|
|
```

- split
|
|
|
|
```python

>>> train_dataset, test_dataset = dataset.split(split_ratio=0.7)
|
|
>>> test_dataset, valid_dataset = test_dataset.split(split_ratio=0.5)
|
|
|
|
>>> len(train_dataset), len(test_dataset), len(valid_dataset)
|
|
(700, 150, 150)
|
|
```
|
|
|
|
- merge
|
|
|
|
```python
|
|
>>> ds_1 = sv.DetectionDataset(...)
|
|
>>> len(ds_1)
|
|
100
|
|
>>> ds_1.classes
|
|
['dog', 'person']
|
|
|
|
>>> ds_2 = sv.DetectionDataset(...)
|
|
>>> len(ds_2)
|
|
200
|
|
>>> ds_2.classes
|
|
['cat']
|
|
|
|
>>> ds_merged = sv.DetectionDataset.merge([ds_1, ds_2])
|
|
>>> len(ds_merged)
|
|

|
|
>>> ds_merged.classes
|
|
['cat', 'dog', 'person']
|
|
```
|
|
|
|

|
|
|
|
```python
|
|
>>> dataset.as_yolo(

<br/> In this video, we explore real-time traffic analysis using YOLOv8 and ByteTrack to detect and track vehicles on aerial images. Harnessing the power of Python and Supervision, we delve deep into assigning cars to specific entry zones and understanding their direction of movement. By visualizing their paths, we gain insights into traffic flow across bustling roundabouts... </p>

|
<br/> Discover the incredible potential of Meta AI's Segment Anything Model (SAM)! We dive into SAM, an efficient and promptable model for image segmentation, which has revolutionized computer vision tasks. With over 1 billion masks on 11M licensed and privacy-respecting images, SAM's zero-shot performance is often competitive with or even superior to prior fully supervised results... </p>
