In this paper, a novel motion-information-based 3D video coding method is proposed for texture plus depth video, which addresses the issue that the traditional motion estimation methods cannot work well for all types of motion.
The global motion information is exploited to :
1. project the reference frames to the view of current-to- be-encoded frame,
2. The motion compensated virtual frame becomes more similar to the current-to-be-encoded frame.
With the computer graphic sequences, for H.264, the average gain of texture and depth coding are up to 2 dB and 1 dB, respectively. For HEVC and HD resolution sequences, the gain of texture coding reaches 0.4 dB.
