Abstract
A video correlation tracking system captures a first image frame and identifies one or more reference patches in that image frame. In a successive image frame, the new location of a reference patch is estimated with a dead reckoning algorithm, and a trial patch is placed at that location. The system cross correlates each reference patch with its corresponding trial patch, the results of which are used to make corrections to the dead reckoning algorithm, register successive image frames, and determine at which reference patch processing resources should be concentrated.
