Asymmetric stereoscopic video coding can save the bitrate and maintain the overall visual quality of three dimensional perception. But for mobile three-dimensional television, the original full resolution restoring is complex for the decoder. In this paper, a decoding and up-sampling optimization scheme for asymmetric stereoscopic video coding is proposed, in which macroblocks encoded with SKIP mode...
A depth image coding method is proposed for 3DTV system in this paper. The proposed method is based on edge enhancement algorithm, considering the fact that the quality of synthesized virtual viewpoint images will be greatly affected by boundary regions in depth image. Using the process of edge extraction and slice-adaptation, the proposed method utilizes different quantization parameters for different...
In 3DTV system, virtual view generation can be accomplished by depth image-based rendering (DIBR) system. And, depth map is key side information for generating virtual image by using DIBR technique in 3DTV system. Before compressing, depth map need to be quantified. But, which quantification method should be choose or how to transform depth information is still a contentious issue. In this paper,...
