Quality-Efficient Upsampling Method for Asymmetric Resolution Stereoscopic Video Coding With Interview Motion Compensation and Error Compensation

摘要

In asymmetric resolution stereoscopic video coding (ARSVC), to reduce the bitrate required for bandwidth-limited channels, each downsampled right-view frame is a quarter the size of the corresponding left-view frame and will be upsampled to the original size by the decoder. In this paper, two upsampling methods for ARSVC are proposed. The first proposed method integrates the traditional Wiener filter-based method and the interview prediction scheme by incorporating the information from the similarity between the left-view and right-view frames. By compensating for the prediction errors, the second proposed method further improves the quality of the upsampled images obtained by the first proposed method, especially in the sequences with heavy irregular textures.
