In 3D video coding, some dependent-view coding tools may utilize derived disparity vectors (DV) to locate inter-view correspondences, such as the Backward ...
In this paper, a sparse DV field is synthesized from the depth map of a coded reference view to provide the DVs required by dependent-view coding tools in TFCO.
Abstract. We propose a rate-distortion-optimized framework that incorporates view synthesis for improved prediction in multiview video coding.
Abstract— This paper presents efficient coding tools for depth data in depth-enhanced video formats. The method is based on the high-efficiency video codec ...
