Abstract

The invention belongs to the technical field of video encoding and decoding, in particular to a video encoding and decoding method in which graphics and images coexist. The text, graphics area and remaining undetected parts are detected based on depth learning and processed as image area. Then, the graphics region and the image region are decoded and decoded respectively. The image region is encoded and decoded by the traditional coding and decoding method. The graphics area is stored in the form of vector graphics, which has the advantage of greatly reducing the video storage space. The scheme can also greatly save decoding time and improve decoding efficiency, and the video resolution is reduced while the sharpness is not degraded.

Description

technical field [0001] The invention belongs to the technical field of video encoding and decoding, and in particular relates to a video encoding and decoding method in which graphics and images coexist. Background technique [0002] Computers have opened the digital era of information processing, so that various types of data can be processed by computers through digitization, but oversampling in the digitization process also introduces a large amount of data redundancy. Especially video data, uncompressed original The large amount of video data is still unbearable for storage and transmission, so video compression has always been one of the hot research issues in the multimedia field. [0003] At present, most of the ordinary video codec technologies are coded based on one image format, compressed into H.264, H.265 or MPEG format, and then decompressed into the source image format for playback. The resources occupied by the codec process Many, high bandwidth, low efficien...
