Paper Abstract

Three-dimensional (3-D) video systems are expected to be a next-generation visual application. Since multiview video for 3-D video systems is composed of color and associated depth information, its huge requirement for data storage and transmission is an important problem. We propose a rendering-oriented multiview video coding (MVC) method based on chrominance information reconstruction that incorporates the rendering technique into the MVC process. The proposed method discards certain chrominance information to reduce bitrates, and performs reasonable bitrate allocation between color and depth videos. At the decoder, a chrominance reconstruction algorithm is presented to achieve accurate reconstruction by warping the neighboring views and colorizing the luminance-only pixels. Experimental results show that the proposed method can save nearly 20% on bitrates against the results without discarding the chrominance information. Moreover, under a fixed bitrate budget, the proposed method can greatly improve the rendering quality.
