Abstract:
Embodiments of the present invention provide methods and apparatuses for coding and decoding a depth map. The coding method includes: obtaining prediction data corresponding to a current image block of the depth map, obtaining a predicted pixel value from the prediction data according to a preset step, and calculating a first average value of the prediction data according to the predicted pixel value, where the preset step is a positive integer except 1; obtaining a residual of the current image block according to the first average value of the prediction data and a pixel value of a pixel of the current image block; and coding the residual of the current image block. In this way, coding and decoding efficiency can be improved.

Claim (Index 16):
The apparatus according to  claim 15 , wherein the processor is further configured to perform one selected from the group consisting of:\n (a) adding the first average value of the prediction data of the current image block and the residual of the current image block to obtain the pixel value of the pixel of the current image block; and (b) adding the first average value of the prediction data of the current image block and the residual to obtain an average pixel value of the current image block, and use the average pixel value of the current image block as the pixel value of the pixel of the current image block.
