Abstract

Joint source-channel coding has attracted substantial attention with the aim of further exploiting the residual correlation residing in the encoded video signals for the sake of improving the reconstructed video quality. In our previous work, a first-order Markov process model was utilized as an error concealment tool for exploiting the intra-frame correlation residing in the Wyner-Ziv (WZ) frame in the context of pixel-domain distributed video coding (DVC). In this contribution, we exploit the inter-view correlation with the aid of inter-view motion search in distributed multi-view video coding (DMVC). Firstly, we rely on the system architecture of WZ coding invoked for multi-view video. Then we construct a novel mesh-structured pixel-correlation model from the inter-view motion vectors (MVs) and derive its decoding rules for joint source-channel decoding. Finally, we benchmark the attainable system performance against the existing pixel-domain WZ (PDWZ) coding based DMVC scheme, where the classic turbo codec is employed. Our simulation results show that substantial bitrate reductions are achieved by employing the proposed motion-aware meshstructured correlation modelling technique in a DMVC scheme.
