Abstract
A block matching motion estimation algorithm uses reduced precision data when comparing pictures in the block to be compressed with pictures in a reference block. This yields a plurality of best match candidates. The average of the best match candidates, excluding those candidates which fall outside a predetermined cluster boundary, is determined and then a second search is performed focused on this average. In this way, the amount of hardware for the block matching algorithm is decreased and the speed of its operation is enhanced.
