VVC currently under development is the latest video coding standard. VVC adopts many new coding technology or improve the original technology to enhance the coding efficiency on the basis of HEVC, at the cost of significantly increased computational complexity, which limits the industrialization and application of the VVC. To address this issue, an efficient CU partition method is presented. This method can effectively reduce computational complexity while preserving encoding efficiency. The proposed method utilizes the texture information and residual coefficient distribution of the CU to skip the low-probability CU partition types in advance. Experimental results illustrate that under the common test conditions, our proposed fast algorithm achieves 52.3% of the coding time saving while the BD-BR only increases by 1.31%, and the objective quality of the video remains basically unchanged.
