Abstract
Video coding is necessary to transmit large amounts of video information. HEVC, which is the latest video coding standard, includes many advanced tools to achieve higher coding efficiency than previous standards, such as MPEG-1/2/4 and H.264/AVC. In particular, new techniques in inter prediction, such as skip, merge, and advanced motion vector prediction (AMVP) modes, drastically improve coding performance by reducing temporal redundancies between consecutive frames within a video. However, the skip mode, which does not perform a motion estimation, can deteriorate the coding performance, because of inaccurate motion vector prediction in videos with fast and complex motions. In order to solve this problem, a novel skip motion estimation method is proposed for efficient inter coding in HEVC. Unlike the conventional skip mode, the proposed skip mode performs the motion estimation, and then transmits the associated motion information. Experimental results demonstrate that the proposed method achieves the high coding performance with the low decoding complexity.
