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 stereoscopic video coding method is proposed based on view warping. In the method, the right view is represented by the residual map between the original view and the warped right views. At the decoder, the right view is reconstructed based on the available information from left view. Thus, the transmitted bitrate can be largely reduced and the reconstructed view quality can be largely improved. Experimental results shows that the proposed method can significantly save the bitrate and can achieve superior reconstruction quality.
