4×4 Intra-prediction Selection Method for H.264/AVC
Tao Lin · Microcomputer applications · 2006
A efficient 4×4 Intra-prediction mode selection method based on statistic is proposed. According to RD cost values of Inter and 16×16 Intra-prediction, this method decide whether 4×4 Intra-prediction can be skipped. In this way, it considerably save coding time of 4×4 Intra-prediction with only a little PSNR degradation and reducing bit rate. Compared with other fast methods, our method involves no additional computational complexity and can be implemented very easily.
