Abstract

The invention discloses a video compression method, a video decompression method, a video compression device, a video decompression device, an electronic device and a storage medium, wherein the video compression method comprises the following steps: obtaining a free viewpoint video frame, the video frame comprising a spliced image formed by synchronous texture maps of a plurality of viewpoints and depth maps of corresponding viewpoints; identifying a texture map area and a depth map area in the spliced image; encoding the texture map region by adopting a preset first encoding mode, and encoding the depth map region by adopting a preset second encoding mode to obtain a compressed video frame, wherein the second coding mode is a coding mode based on a region of interest. According to the scheme, the compression loss of the image can be reduced, so that the image quality of the free viewpoint video can be improved.

Description

technical field [0001] The embodiments of this specification relate to the technical field of video processing, and in particular, to a video compression method, decompression method, device, electronic equipment, and storage medium. Background technique [0002] Video data is data that supports video playback for users to watch. Usually, video data only supports users to watch from one viewing angle, and the user cannot adjust the viewing angle. [0003] Free viewpoint video is a technology that can provide a viewing experience with a high degree of freedom. Users can adjust the viewing angle through interactive operations during the viewing process, and watch from the desired free viewpoint, which can greatly improve the viewing experience. [0004] At present, in order to realize the playback of free-viewpoint video, there is currently a free-viewpoint video generation method based on the stitching of texture maps and depth maps. , the spliced ​​images at multiple frame ...
