A multi-view video plus depth coding method based on view warping and bit allocation

Three-dimensional (3D) video technology is becoming increasingly popular, as it can provide stereoscopic perception and immersive experience to end users. In this paper, a novel multi-view video plus depth coding method is proposed based on view warping and bit allocation. In the method, depth information is used to warp the left view to build a residual map of right view. Then, rational bit allocation between texture and depth is implemented. At the decoder, the right view is reconstructed based on the available information from left view. Experimental results show that the proposed method can significantly improve the performance of view synthesis under the total bitrate constraint.
