Abstract

Distributed compressed sensing coding of video signals is the base and the key for realizing high-efficiency transmission of the video signals. Side information is acquired by motion search and homographic matrix compensation time interpolation by aiming at the problems of side information accurate acquisition and reconstruction algorithm in distributed compressed sensing coding, and decoding can be performed through fusion of the side information after the coset index is received by a decoding end. Smooth constraining is performed on decoding pixel points by introducing a Huber-Markov random field prior probability model in joint decoding reconstruction so as to obtain better reconstruction quality. According to a distributed video coding and decoding technical method based on compressed sensing, the method of "independent coding and joint decoding" is adopted, and complexity is transferred to the decoding end from a coding end so that complexity of coding operation is enabled to be low, and the method is suitable for resource constrained video coding equipment in a wireless network.

Description

technical field [0001] The invention belongs to the technical field of compressed sensing and distributed video coding, and in particular relates to a distributed video compressed sensing coding technology method. Background technique [0002] In the traditional video coding framework represented by H.26x and MPEG series standards, the coding end undertakes a large number of calculations such as transformation, quantization, entropy coding, and motion estimation / motion compensation. Among them, motion estimation and motion compensation account for most of the computation of the entire system, resulting in much greater computation and complexity at the encoding end than at the decoding end. Therefore, these codecs are very suitable for video systems that encode once and decode multiple times, such as broadcast TV, VOD and DVD. [0003] However, in some video application scenarios, such as new video applications such as mobile video communication, wireless video surveillance,...
