Abstract:

Present distributed video coding (DVC) approaches assume the correlation channel to be side-information independent (SII). We have recently demonstrated that in reality the correlation channel in video is side-information dependent (SID) and that DVC systems which make SII assumptions suffer a significant performance penalty depending entirely on the correlation statistics of the video data. In this paper, we present a novel spatial domain unidirectional DVC codec which is based on a novel SID technique enabling advanced correlation channel estimation at the decoder starting from a partial knowledge of it. Experimental results show that the proposed codec achieves superior performance compared to the state-of-the-art in Wyner-Ziv video coding while operating without a feedback channel.
