Bitrate reduction in asymmetric stereoscopic video with low-pass filtered slices

In 3D video compression, similarities between the two views can be helpful in efficient video compression. One way to take advantage of these similarities is to have one of the views at high quality and lower the quality of the other view. In this study, we measured the bitrate reduction resulted from low-pass filtering horizontal slices in both views, with the corresponding slice in the other view kept at the original quality. Results showed that we can reduce the required bitrate for the stereoscopic video while keeping the 3D video quality close to the original video.
