摘要
AVS3 is the next generation video coding standard and is being developed by the audio and video standard (AVS) working group of China. As the successor of AVS2, AVS3 is designed to achieve a great coding efficiency beyond AVS2 as well as H.265/HEVC. In this paper, we propose a novel block partition method for intra coding, named derived tree block partition (DTBP), based on the block partition structure in AVS3. By further splitting a leaf node of the partition tree to quad split types or asymmetric types, the signaling efficiency and the flexibility of partitioning asymmetric texture can be improved. When implemented on HPM3.1, up to 1.14% and an average 0.61% BD-rates are achieved under AII-Intra configuration.
