multi-object tracking (MOT)

Maintaining a consistent identity for each of several tracked objects across a video, including through brief occlusion.

Multi-object tracking (MOT) maintains a consistent identity for each of several simultaneously tracked objects across a video sequence, solving a frame-to-frame assignment problem between new detections and existing tracks (often combined with per-track Kalman filtering) and reasoning about what to do with a track that briefly disappears behind an occlusion before it reappears.

Examples

MOT keeps the same identity on a pedestrian who walks briefly behind a parked van and reappears a few frames later, rather than assigning them a brand-new ID.
