APPARATUS AND THE METHOD FOR PERFORMANCE IMPROVEMENT OF PIXEL DOMAIN WYNER ZIV ENCODER AND DECODER

摘要

PURPOSE: A pixel domain distributed video codec apparatus and an encoder and a decoder using the same are provided to offer a superior image quality based on the correlation and statistical redundancy by assigning an analysis code. CONSTITUTION: In a pixel domain distributed video codec apparatus, an encoder and a decoder assign analysis code using the correlation and statistical redundancy about the concentration of a difference between a WZ(Wyner-Ziv) frame and an SI(Side Information). A gray encoder(104) assigns the analysis code.
