Embodiment Construction

[0076] The method of the present invention will be further described in detail below in conjunction with the accompanying drawings. Only the brightness component Y is taken as an example, and the compression steps of the color difference components U and V are the same as the brightness components.

[0077] The invention proposes a method for compressing and decompressing binocular stereoscopic video based on fractal and H.264. Wherein, the left channel is used as the base layer and the right channel is used as the enhancement layer for encoding respectively. First, use H.264-based intra-frame prediction coding for the starting frame (I frame) of the left purpose, and obtain the reconstructed frame after filtering (as the reference frame of the base layer and enhancement layer), and then perform block motion compensation prediction on the left purpose P frame (MCP) encoding, calculate the pixel sum and pixel square sum of the sub-block related to the sub-block domain and the p...

Abstract

The invention provides a fractal and H.264-based binocular three-dimensional video compression and decompression method, which comprises the following steps of: performing H.264-based intra-frame prediction coding on a starting frame (frame I) of a left eye, performing filtration to obtain a reconstructed frame (which can be used as a reference frame), performing block motion compensated prediction (MCP) coding on a frame P of the left eye, recording fractal parameters of blocks in each optimal matching process, substituting the fractal parameters into a compression iteration function system to obtain a predicted frame of the frame P respectively, and performing filtration to obtain a reconstructed frame; performing prediction on a starting frame of a right channel from the frame I of a base layer in a disparity compensated prediction (DCP) way; performing MCP and DCP on the frame P, and selecting a result with a minimum error as a prediction result for coding; and compressing residual frames of the frames I and P by utilizing entropy coding CALCV, and compressing the fractal parameters by utilizing signed index Columbus coding.

Description

Technical field: [0001] The invention belongs to the field of video compression coding, and relates to the compression coding of binocular stereoscopic video. Under the premise of ensuring that the peak signal-to-noise ratio (PSNR) remains basically unchanged, it greatly reduces the computational complexity and improves the compression ratio, and provides binocular stereoscopic video coding. It lays the foundation for the real-time application of fractal video and further improves the performance of fractal video compression coding. Background technique: [0002] Compared with previous video coding standards, H.264 has better compression performance and "friendliness" for network transmission. The excellent compression performance of H.264 is due to the accumulation of the effects of various new technologies (see Wiegand T Sullivan, G J Bjontegard G, et al.Overview of the H.264 / AVC video coding standard[J].IEEE Transaction on Circuits and Systems Video Technology,2003,13(7)...
