We design a video codec to encode the depth video for 3D video system. Compared with using the H.264/tAVC based state-of-the-art encoder, the proposed encoder is capable of further improving compression ratio with about 30% while maintaining the same image quality.

Design a depth codec to encode the depth video more efficiently;

Design a depth codec to encode the depth video more efficiently;

Big data volume;

Traditional codec is designed to encode color videos;

Improve coding efficiency;

Compatible with standards;

Co-design with human 3D perception, 3D display, view synthesis, and 3D content generation/processing.

Basic idea: Exploiting different regional responses of the distortion in depth video.

Basic idea: Build a many-to-one mapping relation between depth distortion and rendering position error.

Our schemes can effectively improve compression ratio and visual quality.
