Side information plays a key role in the performance of a Distributed Video Coding (DVC) system. However, the generation of side information often relies on complex motion estimation/interpolation operation. The correlation between the source data and the side information, sometimes referred as virtual channel, is also very difficult to model accurately. In this paper, we propose a bitwise prediction...
A novel concept of channel division to improve the performance of distributed video coding is proposed in this work. At the decoder, the proposed algorithm partitions each side information frame into multiple regions with different expected distortions. It is shown that the partitioning is equivalent to the division of the virtual noisy channel from the encoder to the decoder into multiple channels...
Side information generation is a major function in the distributed video coding (DVC) scheme. It significantly determines the performance of the codec. In this paper, an improved technique is proposed for the temporal side information generation process. In the forward motion estimation, various block sizes and a weighted distortion function are adopted in the mode decision step. Motion vectors of...
