Problems solved by technology

However, the direct use of traditional compression sampling methods for compression coding has the disadvantage of low compression efficiency [see literature: [5] V.K.Goyal, A.K.Fletcher, S.Rangan, Compressive Sampling and Lossy Compression, IEEE Signal Processing Magazine, voll.25 , no.2, pp.48-56, Mar 2008]

Abstract

The invention discloses a compressive sampling-based (CS-based) video coding / decoding system and a method thereof and relates to the technical field of image compression. The video coding / decoding system consists of a CS-based video coder subsystem (100) and a CS-based video decoder subsystem (200), wherein the CS-based video coder subsystem (100) is used for realizing compressive coding on an input video sequence image at a video sending end to generate a video compression code stream, and the CS-based video decoder subsystem (200) is used for realizing decoding on the received video compression code stream at a video receiving end to reconstruct an original video sequence image. According to the CS-based video coding / decoding system disclosed by the invention, the compression efficiency and the quality of the reconstructed image can be effectively increased while low-complexity coding is performed, and the application requirements of a wireless video camera, a wireless video monitor and the like are met.

Description

technical field [0001] The invention relates to the technical field of image compression, in particular to a compression sampling-based video codec system and method thereof. Background technique [0002] The traditional video coding method is to reduce the redundant information of the adjacent frame difference image by introducing motion estimation and motion compensation technology at the coding end, which effectively improves the coding efficiency of the video image. This video encoding method adopts joint encoding and joint decoding technology, and has the characteristics of complex encoding end and relatively simple decoding end. This encoding method is suitable for on-demand services such as broadcasting and video streams, where the video sequence only needs to be encoded Once but requires decoding on multiple terminals. However, this traditional video encoding method is not suitable for emerging video encoding applications that require hardware resources at the encod...
