A fast-search motion estimation method and its VLSI architecture

摘要

An efficient search algorithm for block motion estimation isnproposed in this paper. By using fuzzy reasoning, the algorithm canndetermine the motion vectors of image blocks quickly and correctly. Ournexperimental results show that the proposed algorithm performs betternthan other search algorithms, such as 3SS, CS, PHODS, 4SS, BBGDS, SES,nPSA, and GPS. The VLSI architecture of the algorithm has been developed,nand in simulation it yields a search rate of 683 000 blocks/s with anclock rate of 66 MHz
