Abstract

Aiming at the problem of multi-type tree division structure in coding unit(CU) division in versatile video coding(VVC), this paper proposed a fast division algorithm based on the orientation characteristics and spatial complexity of CU subblocks. Firstly, this paper used the overall texture complexity of CU to classify the current CU and filtered out the CU that was not divided. Then, this method used the difference in the characteristics of different division directions of subblocks to decide the CU division direction in advance. Finally, the algorithm used the complexity difference feature between the middle region and the edge region of CU to determine whether to skip the ternary tree(TT) division, which further reduced the number of candidate list division patterns. The experimental results show that compared with the official test platform VTM10.0, the encoder reduces the encoding time by 40.25% at the cost of increasing the average output bit rate by 1.12%, indicating that the algorithm can achieve shorter encoding time with less quality loss in versatile video coding.
