Problems solved by technology

[0024] However, currently based on image 3 The encoding process of the weights is too complicated, which is not conducive to CU segmentation
In addition, there is room for further improvement of conventional RDO-based CU partitioning

Abstract

A method and product for coding unit (CU) partitioning of a video frame based on a regional directivity disparity sum in high efficiency video coding (HEVC).

Description

technical field [0001] The present invention relates to the field of image and video processing, and more specifically, to a method, device and computer program product for dividing coding units (CUs) of virtual reality 360-degree video frames in High Efficiency Video Coding (HEVC). Background technique [0002] Virtual reality video is to use a professional camera to capture the image information of the entire scene, the video is spliced ​​by software, and played by special equipment. It also provides viewers with various functions of manipulating images, which can zoom in, zoom out and move in various directions to watch the scene, thus simulating and reproducing the real environment of the scene. In a virtual reality system, multiple cameras capture a 360-degree scene and stitch it all into a spherical video, creating a 360-degree video. When we encode 360-degree video, we have to project spherical video into planar video to accommodate widely used coding standards such ...
