Asymmetric multi-view video coding based on chrominance reconstruction

Three-dimensional video (3DV) technology is becoming increasingly popular, as it can provide high quality and immersive experience to end users. Huge amount of data for storage and transmission is an important problem to be solved. In this paper, an asymmetric MVC method is proposed. Color correction is first performed as a preprocessing step to provide consistent color information among views. Then, all color corrected views are classified into color views and non-color views. The chrominance information in non-color views is all discarded and only preserved in color view in MVC codec. Thus, a large amount of coding bitrate can be saved. At the decoder, a chrominance reconstruction algorithm is presented to achieve accurate color reconstruction for those non-color views. Experimental results show that the proposed method can achieve large bitrate saving against the results compressed with the original JMVM codec. Moreover, the proposed method can obtain better reconstruction quality without noticeable quality degradation.
