Abstract
An apparatus for estimating motion vectors between a current frame and a reference frame of video signals employs a set of moving object patterns, each of the, moving object patterns representing a predetermined pattern of movement for at least one moving object and comprises; unit for storing the set of moving object patterns; unit for dividing the current frame into a multiplicity of search blocks of an identical size; unit for producing a search region from the reference frame corresponding to one of the search blocks; unit for producing a plurality of candidate blocks of the identical size in the search region; and unit for comparing the one of the search blocks with the plurality of candidate blocks in the search region on the basis of each of the moving object patterns to produce a codeword index for a selected moving object pattern and a motion vector representing the displacement of one of the moving object(s) defining the selected moving object pattern.
