Embodiment Construction

[0021] Most of the existing distributed multi-view video coding frames are arranged in a checkerboard pattern, that is, key frames (K frames) and non-key frames (WZ frames) are arranged at intervals. In this arrangement, side information between viewpoints and time The side information adopts disparity vector interpolation method and motion compensation interpolation method respectively. However, this arrangement is only applicable to the case where multiple viewpoints are distributed on the same straight line. When multiple viewpoints are distributed on a non-linear line, the quality of side information between viewpoints is relatively low when using this frame arrangement in a multi-view distributed video coding system. Low, resulting in relatively low quality of decoded video frames, there is an urgent need for a multi-view frame arrangement method suitable for non-linear distribution.

Abstract

The invention belongs to the technical field of compressed sensing and distributed type video coding, and provides a multi-viewpoint distributed type video encoding and frame arranging method based on compressed sensing, wherein the multi-viewpoint distributed type video encoding and frame arranging method based on compressed sensing is suitable for nonlinear line distribution, the quality of side information between viewpoints is improved, and then the quality of decoded video frames is further improved. According to the technical scheme, an encoder part and a decoder part are included in the multi-viewpoint distributed type video encoding and frame arranging method based on compressed sensing. The encoder is adopted in the encoding step of key viewpoints and non-key viewpoints, wherein firstly, according to the arrangement sequence of the viewpoints, one key viewpoint, one key viewpoint and one non-key viewpoint are sequentially arranged, and frames in each viewpoint are arranged in the mode that key frames and non-key frames are arranged at intervals; secondly, the frames are divided into two kinds, one kind of frames are the key frames of the key viewpoints and the non-key viewpoints, the key frames are encoded according to the compressed sensing theory, and the non-key frames are encoded through the distributed type video coding method. The multi-viewpoint distributed type video encoding and frame arranging method based on compressed sensing is mainly used in the compressed sensing and distributed type video coding.

Description

technical field [0001] The invention belongs to the technical field of compressed sensing and distributed video coding, and in particular relates to a multi-viewpoint distributed video coding and frame arrangement method based on compressed sensing. Background technique [0002] In traditional video coding technologies, whether it is the H.26X series or the MPEG series, the encoding end removes time and space redundancy through inter-frame prediction and DCT transformation to obtain high compression efficiency, which makes the entire system more efficient for the encoder's computing power and The memory capacity requirement is much higher than that of the decoder. [0003] At present, most multi-view video coding (MVC) methods are formed by extending the H.264 / AVC standard. MVC often has a more complex predictive coding structure than single-view video signal coding, and its coding algorithm complexity is far greater than that of single-view video coding algorithms. Theref...
