H.264中基于边缘方向检测的帧内预测模式选择算法
One intra prediction mode selection algorithm based on edge direction detection in H.264
摘要
Abstract
Motion estimation is the most complex part in H. 264. Intra prediction is an important part of motion estimation. There are a number of intra prediction modes in H. 264, which no doubt greatly increase encoding complexity. In intra prediction, the way of choosing prediction method is rate distortion optimization or using correlation properties. For complexity problem, the paper provides an improved intra prediction mode selection algorithm. This algorithm uses a new detection method to detect the pixel correlation in the direction of mode selection. Test results show that the algorithm has reduced the computational complexity and increased the encoding speed highly in the premise of ensuring video quality.关键词
