A new hardware algorithm for the block matching video motion estimation is presented. The algorithm works in the full-search fashion but unlike the Full-Search Block Matching Algorithm (FSBMA) it adjusts the number of computations dynamically to variable picture contents. Due to incorporated mechanism of data-driven thresholding, the proposed algorithm performs as four times as less operations comparing to the FSBMA while maintaining the same quality of results. Its hardware implementation is simple and compact. A supportive hardware design as well as simulation results on benchmarks are outlined.
