Distributed encoding and decoding method and system of hvs & roi

A Distributed coding method and system of the HVS & ROI, belonging to the distributed coding method and system, which consists of two parts encoder and decoder. The combined encoder HVS model JND Wyner-Ziv input video frame is divided into macroblocks C and AC macroblock, and extracting the ROI macroblock AC, for each K frame WZ frame independently coded macroblock; decoder received jointly decoding a code stream. Since the present invention is the introduction into the human visual system HVS JND model, reducing the threshold JND processing and transmission of data about the work area, reduce the transmission rate, bandwidth and energy saving functions effect; comparison with vigorous present invention, since a large luminance motion glare region extraction ROI ROI, and its entropy coding, in the case of trying not to increase the coding complexity and improve subjective quality.
