H.264/AVC outperforms the previous coding standards thanks to variable block size motion compensation (VBSMC) ranging from 4 × 4 to 16 × 16 in interframe coding. However, this new feature causes extremely high computation complexity when rate-distortion optimization(RDO) is performed using full mode decision. In this paper, we propose an adaptive fast block mode decision algorithm (AFBMD) leveraging...
The main purpose of this paper is to shorten the encoding time of the stereoscopic video with guaranteed encoding quality. Based on the analysis of 3D/2D video encoding Motion Estimate Search Algorithm, this paper proposes a method to introduce S-UMHexagon (Simple UMHexagon) Search Algorithm to H.264 stereoscopic video encoding test model JMVC (Joint Multiview Video Coding). The experimental results...
In H.264, Intra prediction is employed to reduce energy of prediction error to be transmitted. Because the order of Intra frame encoding is from left to right horizontally and from top to bottom vertically, intra prediction reference pels can only appear on the left side or upside of the block to be predicted, so predicted results are not ideal sometimes. In this paper, a new intra 4 times 4 prediction...
