Problems solved by technology

[0010] For disparity estimation, the algorithm based on block matching can usually get more accurate matching results in larger search areas, but for areas with smaller disparity, an excessively large search area will increase the computational complexity. How to adaptively Adjusting the search area to reduce the computational complexity as much as possible while ensuring the accuracy of disparity estimation becomes another key optimization direction in multi-view coding

Abstract

The invention discloses a method for determining an optimal multi-viewpoint video coding mode for coding. The method comprises the following steps of: setting different complexity values for each coding mode according to coding complexities; calculating coding complexity values of a current macro block according to the time-domain relevancy of the same viewpoint, inter-viewpoint relevancy and intra-frame relevancy respectively; determining a coding mode set selectable for the current macro block by adopting a mode transition method according to three calculation results; and selecting a coding mode with minimum rate distortion as a coding mode for the coding of the current macro block. By the method, multi-viewpoint video coding complexity can be effectively reduced on the basis of no reduction in coding efficiency.

Description

technical field [0001] The invention relates to the field of stereoscopic video processing and communication, in particular to a method for determining the best mode of multi-viewpoint video coding for coding. Background technique [0002] Stereoscopic video, with its richer content and more realistic visual experience, is being applied in people's daily life. However, because stereoscopic video contains more information than ordinary video, the basic performance is that stereoscopic video usually contains two or more video sequences, thus occupying more storage and transmission space. [0003] In recent years, with the development of various stereoscopic video technologies, people are no longer satisfied with the stereoscopic experience brought by simple binocular video, and the demand for the degree of freedom of viewing stereoscopic video is also increasing, and the corresponding applications are becoming more and more extensive, such as , free-viewpoint video, 3D TV, et...
