Abstract: Compared with other video coding standards, the inter-frame prediction of HEVC provides higher coding efficiency, leading to higher coding complexity however. This paper presents a new inter-frame prediction algorithm for HEVC to speed up the process. The method is based on motion features of coding unit (CU). It takes different optimization measures according to different motion features to reduce the inter-frame prediction time. Experiments on HM6.0 show that the proposed algorithm can reduce encoding time by about 53.33% for the same performance of the original algorithm.
