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 2):
The method according to  claim 1 , wherein obtaining the residual of the current image block comprises one selected from the group consisting of:\n (a) performing a difference operation between the pixel value of the pixel of the current image block and the first average value of the prediction data of the current image block to obtain the residual of the current image block; and (b) determining a second average value of the data of the current image block according to the predicted pixel value of the data of the current image block, and performing a difference operation between the second average value of the data of the current image block and the first average value of reference data of the current image block to obtain the residual of the current image block.
