Fast Inter-Frame Prediction Algorithm of HEVC Based on Graphic Information
Qian Zhang · Jisuanji kexue yu tansuo · 2014
Since the latest video coding standard HEVC(high efficiency video coding) uses quad-tree recursive structure to divide coding unit(CU), it adds a lot of computation complexity to the inter-frame prediction and makes coding efficiency decline. This paper proposes a fast inter-frame prediction algorithm based on texture information and stationary regions determination, which is aimed to determine the homogeneity regions and the stationary regions to early skip the CU split. The homogeneity regions and the stationary regions can have accurate motion prediction using large CU size, and needn't be split into smaller ones, which will reduce the computation complexity. The experimental results show that the proposed algorithm can achieve a reduction of 34% encoding time on average, with 0.038dB PSNR loss and 0.56% bit rate increase, compared with the original HEVC reference software(HM10.0).
