INTRA-FRAME DEPTH MAP BLOCK ENCODING AND DECODING METHODS, AND APPARATUS

摘要

The present invention discloses an intra-frame depth map block decoding method, including: acquiring, from a bitstream, a depth modeling mode (DMM) used for a depth map block, wherein the DMM is applied to a recursive quadtree (RQT) coding or simplified depth coding (SDC); obtaining a block predicted value of a depth map subblock obtained through segmentation in the DMM according to the DMM; acquiring, from the bitstream, a block offset value of the depth map subblock, and residual information of each pixel in the depth map subblock; and obtaining a reconstruction value of each pixel in the depth map subblock according to the block predicted value, the block offset value and the residual information of each pixel in the depth map subblock.
