Abstract
An improved method for determining optimum motion vectors of video signals employs a similarity measurement between a search block in a current frame and each of a plurality of candidate blocks included in a corresponding search region in a previous frame along with a spatial correlation measurement between pixel data in each of error signals generated from the search block and the candidate blocks. The method comprises the steps of providing error signals, calculating an error function and index of correlation for each of said error signals, and generating a motion vector corresponding to an optimum error signal determined based on error functions and indices of correlation of the error signals.
