A framework of 3D video coding using view synthesis prediction

The advanced 3D video system employs the multi-view video plus depth (MVD) format to support free-viewpoint navigation and comfortable 3D video. Therefore, the prediction structure of the multi-view video coding (MVC) can be used for 3D video coding. The view synthesis prediction method is designed to exploit inter-view correlation using the virtual view generation; hence it is suitable for 3D video coding. In this paper, we propose an efficient framework for 3D video coding using view synthesis prediction to compress multi-view color and depth data simultaneously. We designed the coding procedure of MVD data with four types of view synthesis methods according to the view position. The experimental results showed that the proposed framework improved the coding performance at most 0.9 dB for the multi-view color videos.
