Abstract

This work aims at improving the quality of the side information in distributed video coding. A novel technique for the fusion of multiple side information is developed for this purpose. Based on genetic algorithms, the proposed frame fusion technique incurs no additional complexity at the encoder side, in case of hash-based distributed video coding. Simulation results show a significant improvement in the side information quality compared to other interpolation techniques available in the literature, which greatly improves the rate-distortion performance of a distributed video codec, where the gain in PSNR can reach 7 dB.
