A New Side Information Generation Scheme for Distributed Video Coding

摘要

In this paper, a new side information generation scheme for distributed video coding (DVC) is proposed. The proposed scheme uses classification-based motion estimation and multiple block motion interpolation to generate the side information. Here, classification-based motion estimation tries to find the "true" motion vector of each block, instead of exploiting the highest temporal redundancy between two corresponding blocks in two key frames. Then, multiple block motion interpolation using several motion vectors for each block is performed so that the corresponding matched block in the side information can be interpolated more efficiently. Based on the simulation results obtained in this study, the proposed scheme successfully improves the perceptual quality and the average PSNR (dB) in both side information and reconstructed frames.
