Current models in Wyner-Ziv video coding consider the temporal correlation noise to be side-information independent (SII). This paper goes beyond this assumption and proposes a novel model, of which the parameters are side-information dependent (SID). The proposed model is experimentally validated showing remarkable accuracy improvement over the conventional SII model. Moreover, a novel SID technique for the accurate estimation of the temporal correlation in video is introduced. The proposed technique enables the design of a novel pixel-domain Wyner-Ziv video coding system operating without a feedback channel. Preliminary experimental results show that the proposed codec achieves superior performance compared to the state-of-the-art in pixel-domain Wyner-Ziv coding.
