Abstract: Block motion estimation using full search is computationally intensive, many fast algorithm have proposed to reduce the computation at the expense of less accuracy of motion estimation. In this paper, we present a new fast and efficient search algorithm for block motion estimation. The proposed algorithm is based on the ideas of predicted starting search point, subsampled block distortion measure, center-biased distribution of motion vector, multiple-candidate diamond search. From the experimental results, the proposed algorithm is superior to many other well-known fast algorithms in both quality performance and computational complexity.
