Paper Abstract

We propose an asymmetric-resolution stereoscopic video codec that can be used for commercially available stereo displays. Currently, most stereo video displays are designed for displaying not only stereo video but also conventional single-view video in order to make them compatible to single-view video services. In these systems, the resolution of each input video for stereo mode is half the input resolution for a single-view mode. We propose a stereoscopic video codec to support both single-view and stereo-view services by encoding full-resolution left images and horizontally downsampled right images. However, it is not possible to employ the conventional disparity estimation between the two views because the resolution of the left image is different from that of the corresponding right image. So we propose a stereoscopic video codec based on a new disparity estimation/compensation method that makes use of all the information of the left reference image without downsampling. We achieved a 0.5- to 0.8-dB coding gain with the proposed stereoscopic codec, compared with several conventional stereoscopic coding algorithms.
