A NEW BLOCK-MATCHING CRITERION FOR MOTION ESTIMATION AND ITS IMPLEMENTATION

In this paper, a novel and efficient block-matching motion estimation criterion called Minimized Maximum Error (MiniMax) is considered, The proposed method can save hardware area about 15% with acceptable video performance, A chip which combines the MiniMax matching criterion and the one-dimensional full search algorithm is presented. The ASIC is motivated by the need of the intensive computational demand to perform motion estimation in real-time. The proposed single chip can match the applications of H.261 and MPEG international standards. Chip cascading is allowed for larger searching range applications.
