View synthesis prediction (VSP) is an important tool for enhancing the coding efficiency in the next-generation three- dimensional (3-D) video systems. However, VSP will lead to prediction position errors when the depth maps are corrupted by packet losses during transmission. In order to mitigate the prediction position errors, a novel disparity vector correction algorithm is proposed in this paper...
View synthesis prediction (VSP) is an important tool for improving the coding efficiency in the next generation three-dimensional (3-D) video systems. However, VSP will result in a new type of inter-view error propagation when the multi-view video plus depth (MVD) data are transmitted over the lossy networks. In this paper, this new type of error propagation is characterized and modeled. Firstly,...
In color-plus-depth map three-dimensional (3-D) video representation, color and depth map sequences exhibit different error sensitivities to the overall quality. Recognizing that, in this paper, we propose to exploit the relay cooperation benefits to achieve unequal error protection (UEP) for better quality 3-D video transmission. Specifically, we propose to apply the first best amplify-and-forward...
The research on three-dimensional (3-D) video transmission over wireless networks has gained rapid growth in the last view years and poses more challenges than the conventional two-dimensional (2-D) video. In color plus depth representation, the 3-D video is synthesized from color and depth map and the reconstructed quality is highly affected by color information rather than the depth one. In this...
