Reference

A customizable lightweight Python library for real-time multi-object tracking.

Examples:

>>> from norfair import Detection, Tracker, Video, draw_tracked_objects
>>> detector = MyDetector()  # Set up a detector
>>> video = Video(input_path="video.mp4")
>>> tracker = Tracker(distance_function="euclidean", distance_threshold=50)
>>> for frame in video:
>>>    detections = detector(frame)
>>>    norfair_detections = [Detection(points) for points in detections]
>>>    tracked_objects = tracker.update(detections=norfair_detections)
>>>    draw_tracked_objects(frame, tracked_objects)
>>>    video.write(frame)
