Efficient joint multiscale decomposition for color stereo image coding

With the recent advances in stereoscopic display technologies, the demand for developing efficient stereo image coding techniques has increased. While most of the existing approaches have been proposed and studied in the case of monochrome stereo images, we are interested in this paper in compressing color stereo data. More precisely, we design a multiscale decomposition, based on the concept of vector lifting scheme, that jointly exploits the cross-view and inter-color channels redundancies. Moreover, our decomposition is well adapted to the contents of these data. Experimental results performed on natural stereo images show the benefits which can be drawn from the proposed coding method.
