This work aims at improving the quality of the side information in distributed video coding. Based on genetic algorithms, our proposed technique combines several frames, interpolated using previously developed methods, in a fusion-based approach. Simulation results show a significant improvement in the side information quality compared to other interpolation techniques available in the literature,...
In this paper, we propose the use of multiple description coding to increase the robustness of distributed video coding while keeping good rate-distortion performance. The video sequence is structured into key frames and Wyner-Ziv frames. For each type of frame, two descriptions are generated by a multiple description scalar quantizer and sent on a loss-prone channel. When both Wyner-Ziv descriptions...
Distributed video coding (DVC) is a recent paradigm which aims at transferring part of the coding complexity from the encoder to the decoder. The performance of such a coding scheme strongly depends on the capacity to estimate correlation at the decoder and, consequently, on the side information quality. In this paper we consider a multi-view DVC framework and propose a very efficient dense disparity...
