Problems solved by technology

In the JMVM encoding process, all macroblock coding modes are searched to obtain the optimal macroblock coding mode. This method can obtain high reconstructed image quality, but the method of full search of macroblock coding modes leads to computational complexity. very high

Embodiment Construction

[0024] The present invention will be described in further detail below in conjunction with the embodiments of the drawings.

[0025] The multi-view video signal is mainly composed of multi-view color video and multi-view depth video. Because the optimal macroblock coding mode of multi-view color video and multi-view depth video has strong similarity, such as Figure 2a The optimal macroblock coding mode of the "Ballet" multi-view color video shown and Figure 2b The optimal macroblock coding mode of the "Ballet" multi-view depth video shown. Therefore, when the coding prediction structures of multi-view depth video and multi-view color video are independent of each other, the present invention uses the macroblock coding mode selection of each macro block in the multi-view color video as the corresponding depth in the multi-view video depth video. The coding predictive value of image coding, that is, joint coding of multi-viewpoint color video and multi-viewpoint depth video to red...

Abstract

The invention discloses an encoding method for multi-view video signals and has the advantages that the method uses the optimal macro-block encoding model of each macro-block in all B frames of the multi-view color video effectively, and the searching range of the macro-block encoding model of each macro-block in all B frames of the deep video is reduced on the premise of ensuring the encoding image quality and the encoding compression efficiency in the multi-view deep video encoding process, thus achieving the goal of reducing the calculating complexity of the multi-view deep video encoding and increasing the speed of the multi-view deep video encoding; as a smooth factor is introduced to the optimal macro-block encoding model process of the current macro-block in the multi-view deep video, the distortion property of the encoding rate is ensured and the encoding speed is increased.

Description

Technical field [0001] The present invention relates to a video signal processing technology, in particular to a multi-viewpoint video signal coding method. Background technique [0002] Free-viewpoint television (FTV, Free-viewpoint Television) is one of the three-dimensional video systems with advanced visual media modes, and contains visual functions that are not available in traditional two-dimensional video systems. FTV can well satisfy users to appreciate the scene from any angle, reflecting the immersive feeling. The rise of this new media has attracted wide attention from many experts and scholars at home and abroad. The core technology of FTV is multi-viewpoint video signal coding and decoding and real-time virtual viewpoint image rendering. The International Organization for Standardization JVT (Joint Video Team, Joint Video Experts Group) proposed the structure of MVD (multi-view video plus depth), that is, the color video of N viewpoints and the depth video informatio...
