Disparity-compensated coding using MAC for stereoscopic video

We propose a novel disparity-compensated coding algorithm using MAC (multiple auxiliary component) of MPEG-4 for stereoscopic video. MAC was added to the MPEG-4 visual version 2 in order to describe the transparency of the video object. The major difference between the existing coding method and the proposed coding method is the addition of the residual texture coding. The proposed coding method assigns disparity map and residual texture to 3 components of MAC: one component for disparity map and the remaining 2 components for the luminance and chrominance data of the residual texture, respectively.
