ABSTRACT |
Variable block-size motion estimation (VBSME) has become an important technique in H.264/AVC to improve video quality. The hexagonal search method recently developed, an enhanced hexagonal search algorithm is proposed to further improve the performance in terms of reducing number of search points and distortion where a novel fast inner search is employed by exploiting the distortion information of the evaluated points. Our experimental results substantially justify the merits of the proposed algorithm.
