In video coding standard, motion estimation (ME) always plays an important role in reducing temporal redundancies at the expense of higher computational complexity. Many fast ME algorithms have been proposed to reduce the coding complexity. Some papers focus on applying specific search patterns to reduce the search points within a fixed search range (SR). But there are only a few of them trying to...
Advanced motion vector prediction (AMVP) is one of the most important inter prediction coding tools adopted in the state-of-the-art HEVC coding standard, which does great effect on the coding efficiency. However, the current AMVP design is highly sequential and thus restricts the throughput both on the encoder and the decoder sides. To facilitate the parallel processing and enlarge the throughput,...
Higher-order motion models were introduced in video coding a couple of decades ago, but have not been widely used due to both difficulty in parameters estimation and their requirement of more side information. Recently, researchers have put them back into consideration. In this paper, the affine motion model is employed in SKIP and DIRECT modes to produce a better prediction. In affine SKIP/DIRECT,...
