Embodiment Construction
[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0025] A method for coding and compressing depth maps applied to 3DTV and FTV systems. In 3DTV and FTV systems, the input for virtual viewpoint rendering includes viewpoint images and depth maps corresponding to the viewpoint images. The viewpoint images are represented by I and the depth maps by D. . Using the edge information of the depth map D and the motion information of the viewpoint image I, the depth map D is divided into a static non-edge area, a non-edge area inside a moving object, and an edge area; Coding, and using the macroblock coding mode and motion vector determined after the coding of the viewpoint image I in the coding process of the depth map D, combined with the above three area classifications of the depth map D, the fast coding of the depth map D is realized.
[0026] Here, the viewpoint image I can be a color viewpoint...
