METHOD FOR ENCODING STEREO RESIDUAL IMAGE AND APPARATUS THEREOF

摘要

A method for encoding a stereo residual image and an apparatus thereof are provided to change an information storage order according to the characteristic of a stereo residual image, thereby restoring a stereo image with high quality in a lesser bit rate. A method for encoding a stereo residual image comprises the following steps of: performing the wavelet conversion of the residual image of a stereo image and computing the edge tendency of a wavelet subband of the converted image(300,310); setting a threshold value from the computed edge tendency(320); performing the dominant pass of the wavelet subband when the set threshold value is higher than the absolute value of the wavelet subband(330); and applying subordinate pass to the dominant passed subband until a difference between the dominant passed subband coefficient and the coefficient of the stereo image is smaller than a difference between the coefficient of a subband not dominant passed and the coefficient of the stereo image(340).
