The AVS video coding standard employs a robust Rate-Distortion Optimization (RDO) technique to improve compression performance. Although RDO technique can achieve better compression efficiency, it also increases tremendous computational complexity. In order to reduce complexity, this paper proposes a fast intra mode decision algorithm for AVS based on the ranking of Sum of Absolute Transformed Difference...
The latest video coding standard H.264/AVC achieves significant coding efficiency by adopting variable block sizes for inter mode decision. However, this technique brings about high computational complexity since the optimal mode is determined by exhaustively calculating rate-distortion cost (RDcost) of all modes. To solve this problem, fast inter mode decision algorithm is proposed, as follows. Based...
