Abstract

Embodiments of the present invention provide a coding unit division method and device based on high-efficiency video coding HEVC, which divides the acquired specified brightness image into multiple sub-images of the first specified size as the current sub-image to be processed; the acquired The current feature map of the associated image of each sub-image to be processed and the sub-image to be processed are input to the target depth value prediction model to obtain the depth value of the sub-image to be processed; if the depth value of the sub-image to be processed is the first Preset the depth value, determine the sub-image to be processed as a coding unit; if the depth value of the sub-image to be processed is not the first preset depth value, divide the sub-image to be processed into multiple sub-images as the current sub-image to be processed Processing the sub-images, and continuing to determine the division method of each sub-image to be processed until the obtained sub-image is the second specified size. Based on the above processing, the efficiency of CU division can be improved, and further, the efficiency of video encoding can be improved.

Description

technical field [0001] The present invention relates to the technical field of video coding, in particular to an HEVC-based coding unit division method, device and electronic equipment. Background technique [0002] In order to improve the speed of video transmission, before sending the video (which can be called the original video) to the receiving end, the sending end can encode the original video based on the HEVC (High Efficiency Video Coding, high-efficiency video coding) algorithm to obtain the target video, and then, The target video can be sent to the receiving end. [0003] In the prior art, when encoding an original video, a CU (Coding Unit, coding unit) corresponding to each video frame of the original video may be determined first, and then the determined coding unit is encoded to obtain a target video. Specifically, the method for determining the coding unit may include: [0004] For each video frame in the original video, the video frame may be divided into m...
