Abstract

The invention provides a coding block division method and device, a storage medium and an electronic device. The method comprises the steps of determining a target coding block needing to be divided currently in a target frame graph; determining each block division mode supported by the target coding block and a sub-block corresponding to each block division mode; applying a JND model to calculatea JND value of each sub-block; obtaining a threshold interval corresponding to each block division mode, and determining an optimal block division mode in each block division mode based on the JND value of each sub-block and the threshold interval corresponding to each block division mode; and dividing the target coding block based on the optimal block division mode. By applying the method provided by the invention, the JND value of each sub-block is calculated by adopting the JND model, and the optimal block division mode needing to divide the target coding block is determined through the JND value of each sub-block and the threshold interval corresponding to each block division mode. Through the method, the division of the coding blocks can be accelerated, and the video coding time canbe shortened.

Description

technical field [0001] The present invention relates to the technical field of video coding, in particular to a coding block division method and device, storage medium and electronic equipment. Background technique [0002] With the rapid development of multimedia technology, people's demand for high-definition video information consumption is increasing day by day. In order to meet the needs of users, and with the development of a new generation of mobile communication technology and the rise of other multimedia emerging industries, the high-definition and ultra-high-definition video industry has ushered in a basis for development. While improving video clarity and resolution, video data bandwidth will also increase. Videos with high data bandwidth need to occupy a lot of space and data during video transmission and storage. Therefore, in order to reduce the data bandwidth of the video while ensuring the quality of the video, video coding technologies of various coding sta...
