Generating Side Information Using HVSBM for Wavelet-based Distributed Video Coding
The quality of side information influences the overall performance of the Distributed Video Coding (DVC). In this context, this paper proposes a practical scheme of using HVSBM to generate side information for wavelet-based DVC. The decoder uses the hierarchical variable size block matching (HVSBM) motion estimation to do the search process and predict side information, which is used to reconstruct Wyner-Ziv frame jointing with the decoded bit stream of Wyner-Ziv frame. And HVSBM uses the criterion of sum of absolute difference (SAD) to divide block. It shows that at the cost of a little higher complexity overall, the proposed HVSBM scheme obtains more accuracy side information and improves the efficiency of the whole codec.
