Definitions

  • the invention relates generally to Three-Dimensional (3D) video processing.
  • the present invention relates to methods for depth map coding.
  • 3D video coding is developed for encoding or decoding video data (texture) of multiple views simultaneously captured by several cameras as well as associated depth maps.
  • the depth map contains only luma data and no chroma (Cb and Cr) data.
  • the monochrome coding is supported.
  • the ChromaArrayType is equal to 0 (The ChromaArrayType is depending on the syntax element chorma format idc), the chroma intra mode and cbf are not coded any more as shown in Fig. 2.
  • the method 1 removes the chroma intra mode and chroma cbf coding for depth map
  • the method 2 imitates the HEVC range extensions and uses the chroma format idc to control the coding of the chroma intra mode and chroma cbf
  • the method 3 always codes the chroma intra mode in any mode including SDC mode.
  • FIG. 1 is a diagram illustrating the chroma intra mode and chroma cbf coding in current 3D-HEVC;
  • FIG. 2 is a diagram illustrating the chroma intra mode and chroma cbf coding in current HEVC range extensions
  • FIG. 3 is a diagram illustrating the chroma intra mode and chroma cbf coding in the proposed method
  • the chroma intra mode and chroma cbf coding are controlled by ChromaArrayType.
  • ChromaArrayType is equal to 0
  • the chroma intra mode and chroma cbf are not coded.
  • the ChromaArrayType is always set as 0.
  • the syntax element chroma format idc can be removed or be ignored or be limited to 0 for depth map coding.
