In the framework of Wyner-Ziv Coding of Video, the coding efficiency depends on the quality of the side information (SI) at the decoder, where the side information is constructed from the key frames available at the decoder. In this paper, we propose a novel frame interpolation method for Wyner-Ziv coding, where the motion compensation is bidirectional and allows pixelwise estimation. The proposed interpolation method allows to obtain better SI quality than the one obtained by state-of-the-art interpolation methods.
