Author(s): Si-Woong Lee; Seong-Mo Park; Hyun-Soo Kang

Paper Abstract

A fast motion estimation algorithm based on the adaptive search range adjustment (ASRA) is presented. The size of search range for each block is adaptively controlled according to the initial cost at the search center, and then the full search algorithm (FSA) is performed to find the optimal matching block in the adjusted search range. The proposed method is implemented in H.264/AVC reference software (JM) to demonstrate its efficiency over the conventional FSA.
