1. A computer-readable medium comprising software for video processing, which when executed by a computer system, cause the computer system to perform operations comprising a method of:
- receiving video from an overhead view of a scene;
detecting moving pixels in the video;
detecting line segments in the video based on detected moving pixels;
identifying targets in the video based on the detected line segments;
tracking targets in the video based on the identified targets; and
managing tracked targets in the video.
