Multiple description Wyner-Ziv video coding based on decoder multi-resolution motion refinement

In this paper, we consider multiple description video coding (MDVC) for robust transmission over packet loss networks. With the motion compensated prediction, it is known that MDVC suffers from predictive mismatch in presence of transmission losses, where the reference frame received at the decoder...
