supervision-0.9.0

🚀 Added

• Ability to select sv.Detections by index, list of indexes or slice. Here is an example illustrating the new selection methods. (#118)

>>> import supervision as sv

>>> detections = sv.Detections(...)
>>> len(detections[0])
1
>>> len(detections[[0, 1]])
2
>>> len(detections[0:2])
2

• Ability to extract masks from YOLOv8 results using sv.Detections.from_yolov8. Here is an example illustrating how to extract boolean masks from the result of the YOLOv8 model inference. (#101)

>>> import cv2
>>> from ultralytics import YOLO
>>> import supervision as sv

>>> image = cv2.imread(...)
>>> image.shape
(640, 640, 3)

>>> model = YOLO('yolov8s-seg.pt')
>>> result = model(image)[0]
>>> detections = sv.Detections.from_yolov8(result)
>>> detections.mask.shape
(2, 640, 640)

• Ability to crop the image using sv.crop. Here is an example showing how to get a separate crop for each detection in sv.Detections. (#122)

>>> import cv2
>>> import supervision as sv

>>> image = cv2.imread(...)
>>> detections = sv.Detections(...)
>>> len(detections)
2
>>> crops = [
...     sv.crop(image=image, xyxy=xyxy) 
...     for xyxy 
...     in detections.xyxy
... ]
>>> len(crops)
2

• Ability to conveniently save multiple images into directory using sv.ImageSink. An example shows how to save every tenth video frame as a separate image. (#120)

>>> import supervision as sv

>>> with sv.ImageSink(target_dir_path='target/directory/path') as sink:
...     for image in sv.get_video_frames_generator(source_path='source_video.mp4', stride=10):
...         sink.save_image(image=image)

🛠️ Fixed

• Inconvenient handling of sv.PolygonZone coordinates. Now sv.PolygonZone accepts coordinates in the form of [[x1, y1], [x2, y2], ...] that can be both integers and floats. (#106)

supervision-0.8.0

🚀 Added

• Support for dataset inheritance. The current Dataset got renamed to DetectionDataset. Now DetectionDataset inherits from BaseDataset. This change was made to enforce the future consistency of APIs of different types of computer vision datasets. (#100)
• Ability to save datasets in YOLO format using DetectionDataset.as_yolo. (#100)

>>> import supervision as sv

>>> ds = sv.DetectionDataset(...)
>>> ds.as_yolo(
...     images_directory_path='...',
...     annotations_directory_path='...',
...     data_yaml_path='...'
... )

• Support for DetectionDataset.split allowing to divide DetectionDataset into two parts. (#102)

>>> import supervision as sv

>>> ds = sv.DetectionDataset(...)
>>> train_ds, test_ds = ds.split(split_ratio=0.7, random_state=42, shuffle=True)

>>> len(train_ds), len(test_ds)
(700, 300)

🌱 Changed

• Default value of approximation_percentage parameter from 0.75 to 0.0 in DetectionDataset.as_yolo and DetectionDataset.as_pascal_voc. (#100)

supervision-0.6.0

🚀 Added

• Initial Dataset support and ability to save Detections in Pascal VOC XML format. (#71)
• New mask_to_polygons, filter_polygons_by_area, polygon_to_xyxy and approximate_polygon utilities. (#71)
• Ability to load Pascal VOC XML object detections dataset as Dataset. (#72)

🌱 Changed

• order of Detections attributes to make it consistent with order of objects in __iter__ tuple. (#70)
• generate_2d_mask to polygon_to_mask. (#71)
