Abstract

To make an encoder extremely simple by eliminating motion prediction/compensation from encoder, source coding with side information has been investigated based on the Wyner-Ziv theorem as the basic coding principle. However, the frame interpolation at decoder which is essential for redundancy elimination makes erroneous side information when the basic assumption of linear motion between frames is not satisfied. In this paper, we propose a new Wyner-Ziv video coding scheme featuring side matching in the frame interpolation to improve the side information. In the proposed scheme, Wyner-Ziv decoder compensates wrong blocks by side information using side matching and bi-directional searching. The noise reduction in side information allows the proposed algorithm to achieve coding improvements not only in bitrate but also in PSNR. Results of our experiments show improvement of PSNR up to 0.4dB.
