METHODS AND APPARATUSES FOR CODING AND DECODING DEPTH MAP |
摘要 |
Embodiments of the present invention provide methods and apparatuses for coding and decoding a depth map, where the coding method includes: acquiring an intra-frame prediction mode of a current image block of the depth map; determining whether the intra-frame prediction mode belongs to a preset intra-frame prediction mode set; if yes, using a preset intra-frame prediction method to perform coding processing on the current image block, so as to acquire a residual of the current image block. The preset intra-frame prediction method includes a first intra-frame prediction method; and a difference operation is performed between an average pixel value of the current image block and an average pixel value of prediction data of the current image block to obtain the residual of the current image block. |

1. A method for coding a depth map, comprising:
acquiring an intra-frame prediction mode of a current image block of the depth map; determining whether the intra-frame prediction mode belongs to a preset intra-frame prediction mode set; if the intra-frame prediction mode belongs to the preset intra-frame prediction mode set, using a preset intra-frame prediction method to perform coding processing on the current image block, so as to acquire a residual of the current image block; and coding the residual of the current image block. |
