摘要:
Joint coding of depth map video and texture video is provided, where a motion vector for a texture video is predicted from a respective motion vector of a depth map video or vice versa. For scalable video coding, depth map video is coded as a base layer and texture video is coded as an enhancement layer(s). Inter-layer motion prediction predicts motion in texture video from motion in depth map video. With more than one view in a bit stream (for multi view coding), depth map videos are considered monochromatic camera views and are predicted from each other. If joint multi-view video model coding tools are allowed, inter-view motion skip issued to predict motion vectors of texture images from depth map images. Furthermore, scalable multi-view coding is utilized, where interview prediction is applied between views in the same dependency layer, and inter-layer (motion) prediction is applied between layers in the same view.
