Abstract
H.264/AVC video coding has permeated into every aspect of life, a new proposal has been present, which calculate the variance of the eight elements of the block to delete prediction mode selection. But this algorithm is more suitable for smooth changes in the sequence of the images. Therefore, this paper proposes an improved algorithm for intra prediction mode selection to solve the problem mentioned above. Using this method on the ARMv4 phone platform into which has been transplanted the x264; the speed is 13.2% higher than original algorithm when only changing the 4×4 luminance blocks, while 4.86% than the new proposal mentioned abroad. The speed can be improved about 0.5 to 2 fps when I modify the 16×16 luminance and 8×8 chrominance blocks making another progress in intra-coding, bringing H.264/AVC more potential applications.
