  • A block feature matching (BFM) criterion function used for block motion estimation in some the international standards such as H.261, H.263, MPEG1, MPEG2, and HDTV codecs, is proposed in this paper. The complexity and VLSI implementation of real-time block matching motion estimation need to involve the following considerations: the motion searching complexity within a given search window, the basic matching complexity for each matching operation, and the required amount of data fetching from frame buffer to the motion estimation processor. Simulation indicated that the proposed BFM function is very simple and effective, thus the corresponding complexity of block matching computation and the time of data fetching are greatly reduced. Moreover, the BFM function can provide the potential of parallel VLSI implementation. Comparisons of the BFM with other criterion functions are also given in detail.
