Multiview image coding using graph-based approach

Abstract

In this paper, we design a new approach for coding the geometry information in a multiview image scenario. As an alternative to depth-based schemes, we propose a representation that captures the dependencies between pixels in different frames in the form of connections in a graph. In our approach it is possible to directly perform compression by simplifying the graph, which provides a more direct control of the effect of coding on geometry representation. Our method leads to more accurate view synthesis, when compared to conventional lossy coding of depth maps operating at the same bit rate.
