Pre-/post-processing to improve the coding performance of multiview plus depth map
作者：
Highlights：
•
• Multiview plus depth map (MVD) is promising for 3D video system.
• The new design for the MVD is proposed by introducing the pre- and post-processing for depth maps.
• The pre-processing is designed to reduce the bit-rate cost while minimizing quality degradation by an appropriate filtering of depth maps.
• The post-processing is designed to restore the pre-processed depth map.
• In addition, an optimal filter parameter selection scheme is proposed based on a theoretic and experimental analysis of the rate–distortion relationship.
