Fast adaptive motion estimation based on distance prediction
Lijuan Li · Computer Engineering and Applications Journal · 2007
Since most of the existing fast motion search algorithm seldom examine all possible candidates within a search area,they may fail to find the optimum point for sequences having fast and/or random motions.To alleviate this problem,proposes a measure estimating the distance between the current search point and the optimal point,which combines with hierarchical searches.The proposed algorithm improves search speed of sequences with fast and/or random motions as well as PSNR performance.
