Multi-directional diagonal search methodology for object tracking

When investigating the mismatch error pattern to template matching for object tracking, it was found that a similar correlation region or "Vortex Effect Region" exists around an object regardless of the search direction. Finding an object in a grey scale image then requires location of a VER and converging to a minimum within it. Multi-directional diagonal search with origin in the centre of an image using VER minimizes the average search distance to the object giving a significant reduction in search time.
