Side information generation for multiview distributed video coding using a fusion approach

Distributed Source Coding (DSC) aims at achieving efficient compression by locating the source redundancies at the decoder instead of the encoder. Moreover, DSC exhibits many properties like low-complexity encoding or embedded error resilience that make it very convenient for some emerging new applications. Among the many challenging topics related to DSC there is the generation of the Side Information, an estimation made by the decoder of the data being decoded. In the particular field of Multiview Distributed Video Coding (Multiview DVC) this Side Information can be generated by inter-camera or intra-camera interpolation. This paper briefly describes both techniques and proposes two approaches that combine them by evaluating the reliability of each interpolation at the pixel level. 1
