Paper Abstract

In this paper, we propose an algorithm for selective application of sub-pixel Motion Estimation and Hadamard transform in the H.264/AVC video coding standard. The algorithm exploits the spatial interpolation effect of the reference slices on the best matches of different block sizes in order to increase the computational efficiency of the overall motion estimation process. Experimental results show that the proposed algorithm significantly reduces the CPU cycles in the Fast-Full-Search Motion Estimation Scheme by up to 8.2% with similar RD performance, as compared to the H.264/AVC standard.
