Abstract :
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
