Depth map is an image that contains information relating to the distance of the surface of scene objects from a view point.
Pre-/Post-processing to improve the coding Performance of Multiview plus depth map
The scheme proposed here instead focuses on the unique properties of depth map and utilizes them to improve the coding performance of MVD system. the pre-processing stage selectively filters the input depth map to reduce the bit-rate cost while minimizing quality degradation, and the post-processing restores the reconstructed depth map as much as possible.
Boundary Artifacts Reduction in View Synthesis of 3D Video System
This scheme proposed a boundary artifacts reduction method for synthesized views in 3D video system using Projection onto Convex Sets (POCS).
