Fast intra prediction mode decision algorithm in H.264/AVC
Luming Zhou · Journal of Computer Applications · 2008
A fast mode decision algorithm was presented for H.264/AVC intra prediction based on the feature of the block and neighboring block's mode information.The number of candidate mode was reduced,for 4×4 luminance block,from 9 to 1~4.Experimental results show that,compared with the H.264 encoder JM8.6,the proposed scheme reduces coding time by 50%~60% for I-frame while keeping PSNR and bit rate almost unchanged.
