HIERARCHICAL IMAGE DECODING AND ENCDOING METHOD AND APPARATUS THEREOF CAPABLE OF REDUCING COMPLEXITY

摘要

PURPOSE: A hierarchical image decoding and encoding method and apparatus thereof are provided to effectively offer scalable encodement by creating a drift image on a residual image.;CONSTITUTION: A video encoding apparatus combines a residual image with a motion image corrected at a reference frame within an improvement layer(903). The video encoding apparatus creates a bit stream by an image quality layer(905). The video encoding apparatus stores residual difference images in each frame buffer. The video encoding apparatus corrects the movement of the stored images(907). The video encoding apparatus outputs the bit stream for the improvement layer(909).;COPYRIGHT KIPO 2012
