Abstract
A video processing system, method and computer program storage device cooperate to provide a resource and performance efficient sub-pixel motion search operation. Using on the fly calculations it is possible to provide approximations of sub-pixel positions on one image with respect to another image in an image sequence. A sub-pixel position used to set a motion vector for an encoding process may then be identified with reduced processing and memory resources relative to conventional techniques. Also, by later performing a full encoding cost analysis on the earlier identified sub-pixel position, and keeping track of differences, an interpolation accuracy may be dynamically improved by applying the differences to subsequent image frames.
