Abstract
A three-frame difference target-tracking system includes at least one processor configured to generate multiple aligned image frames of a scene. The aligned image frames include first, second, and third image frames. The at least one processor is also configured to identify differences between the first image frame and the second image frame, between the second image frame and the third image frame, and between the first image frame and the third image frame. The at least one processor is further configured to identify a direction of movement of a target in the scene based on the identified differences.
