Abstract

The invention discloses a video encoding and decoding system based on image inpainting predication in the technical field of video processing. The system comprises a macroblock partitioning module, a macroblock predication module, a residual encoding module, a residual decoding module and a macroblock rebuilding module, wherein the macroblock predication module comprises an intra-frame predication submodule, an inter-frame predication submodule, an image impainting predication submodule and a mode selection submodule. In the invention, on the basis of a H.264 mixed video encoding standard system, the image inpainting predication submodule is added, which makes up the deficiency of the traditional video encoding and decoding system; and compared with the traditional video encoding and decoding system H.264, the video encoding efficiency is improved and the system has better adaptability and error resistance.

Description

technical field [0001] The present invention relates to a codec system in the technical field of image processing, in particular to a video codec system based on image restoration prediction. Background technique [0002] Video codec system is crucial for applications such as video storage and transmission. The new generation of international video coding standard H.264 is a highly compressed digital video code proposed by the Joint Video Team (JVT) jointly composed of ITU-T Video Coding Experts Group (VCEG) and ISO / IEC Motion Picture Experts Group (MPEG). Video codec standard. [0003] The video codec system based on the international video coding standard H.264 includes an encoding subsystem and a decoding subsystem. The encoding subsystem is divided into a macroblock segmentation module, an intra prediction module, an inter prediction module, a mode selection module, and a residual encoding module. The decoding subsystem includes a residual decoding module and a macrob...
