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

摘要

The present invention discloses an intra-frame depth map block encoding method, including: acquiring a depth map block to be encoded; when a depth modeling mode (DMM) is applied to a recursive quadtree (RQT) or simplified depth coding (SDC) to encode the depth map block, separately detecting the depth map block by using a DMM1 mode and a DMM4 mode in the DMM, to obtain rate-distortion results of the depth map block in the DMM1 mode and in the DMM4 mode; and determining that a DMM with a smallest rate-distortion result in the DMM1 and the DMM4 is a DMM used during encoding, applying the used mode to the RQT or the SDC to encode the depth map block, and writing the used DMM to a bitstream.

1. An intra-frame depth map block encoding method, comprising:
acquiring a depth map block to be encoded; when a depth modeling mode (DMM) is applied to a recursive quadtree (RQT) or simplified depth coding (SDC) to encode the depth map block, separately detecting the depth map block by using a DMM1 mode and a DMM4 mode in the DMM, to obtain a rate-distortion result of the depth map block in the DMM1 mode and a rate-distortion result of the depth map block in the DMM4 mode; and determining that a DMM with a smallest rate-distortion result in the DMM1 and the DMM4 is a DMM used during encoding, applying the used mode to the RQT or the SDC to encode the depth map block, and writing the used DMM to a bitstream.
