Versatile video coding (VVC) is the la test video coding standard.Compared with high efficiency video coding (HEVC),the compression efficiency is further improved.However,due to the introduction of b inary trees and tri-trees quadtree with nested multi-type tree (QTMT) structure,and the intra-frame angle mode has also increased from 35to 67,resul ting in a sharp increase in coding complexity.In order to reduce the computational complexity,th is paper proposes a VVC intra coding algorithm based on fast coding unit (CU) division an d angle mode decision.First,classify the CU texture complexity according to the adaptive stan dard deviation threshold,and initially reduce the list of division modes; then use the Sobel g radient operator to determine the texture direction,remove the non-optimal direction division mode ; finally eliminate the angles with lower probability according to the statistical results mode.Exp erimental results show that compared with VTM-2.1,this algorithm saves 51.05% of coding time,and Bjontegarrd delta bit rate (BDBR) only increases by 1.98%.
