Claim Text:
1. A computer-implemented surveillance method comprising the steps of: providing a real imaging means forming a pair of first and second images of a real space in a field of view of the imaging means, the field of view having a center; storing the pair of first and second images in non-transitory memory; performing, with a processor, a frame differencing operation on the pair of first and second images to form a resultant image including blobs corresponding to elements in the real space and then storing the resultant image in the non-transitory memory, the frame differencing operation comprising: classifying one of the blobs as the object; tracking the object by moving the imaging means toward the object by an amount corresponding to the distance between the center of the field of view and a center of the object; and continually repeating the tracking step as the element corresponding to the object moves in the real space.
