Wyner-Ziv coding, also known as distributed video coding, is currently a very hot research topic in video coding due to the new opportunities it opens. This paper applies the distributed video coding principles to stereo video coding, to propose a practical solution for Wyner-Ziv stereo coding based on mask-based fusion of temporal and spatial side informations. The architecture includes a low-complexity encoder and avoids any communication between the cameras/encoders. While the rate-distortion (RD) performance strongly depends on the motion-based frame interpolation (MBFI) and disparity-based frame estimation (DBFE) solutions, first results show that the proposed approach is promising and there are still issues to address.
