Abstract

Intra prediction plays an important role in H.264/AVC. The mode fast decision is a significant factor for video coding efficiency in current video coding standard. Therefore, in this paper, the authors propose a method to choose the prediction mode quickly to save coding resource. According to the frame texture characteristics, the authors choose the block size and divide one intra_16×16 block into four intra_8x8 sub blocks with the algorithm. The sub blocks are transformed into frequency domain respectively. According to the number of zero, appropriate intra prediction mode can be decided. Furthermore, by taking advantage of direction relationship, the intra_4×4 sub blocks mode decision can be obtained. The experimental results demonstrate that the algorithm proposed in this paper can save coding time 30-50% while 0.04dB reduction of PSNR.
