RATE-VISUAL-DISTORTION OPTIMIZED EXTRACTION WITH QUALITY LAYERS FOR SCALABLE CODING OF STEREO VIDEOS

Abstract

The Quality Layers concept is proposed and adopted in the JSVM in order to ensure an optimal adaptation in a rate-distortion sense [I]. In this paper it is extended to multiview case for scalable coding of stereo videos. Rate-visual-distortion optimized rate allocation among the views is necessary for efficient transport of 3DTV data over the Internet. This paper addresses a standard compatible approach to solve the problem. Experimental results are presented that demonstrate the effectiveness of the proposed method for several stereo videos.
