The authors present a new block feature matching (BFM) criterion function that can be used for block motion estimation of H.261, H.263, MPEG1, MPEG2, and HDTV codecs. Simulation indicates that the proposed BFM function is very simple and effective, thus the corresponding complexity of block matching computation and data transfer time are greatly reduced. The BFM function can be combined with any fast search algorithm of motion estimation.
