A Fast Algorithm for VVC Intra Coding Based on the Most Probable Partition Pattern List

Compared with High-Efficiency Video Coding (HEVC), Versatile (VVC) has more flexible division and higher compression efficiency, but it also computational complexity. In order to reduce the coding complexity, a fast algorithm based on most probable partition pattern list (MPPPL)and pixel content similarity is proposed. Firstly, MPPPL constructed by using average texture complexity difference of sub-coding unit under different modes. Then, sub-block mean used decide best mode or shorten MPPPL. Finally, selection rules reference lines in intra prediction process are counted unnecessary skipped similarity. The experimental results show that compared VTM-13.0, proposed can save 52.26% encoding time, BDBR (Bjontegarrd delta bit rate) only increases 1.23%.
