Abstract

In order to overcome the performance limitation of the conventional DVC schemes, this paper presents a reliability-based selective encoding scheme based on the pixel-domain Wyner-Ziv residual (PDWZR) video codec. At the decoder, the unreliability of the previously reconstructed WZ frame is investigated and then, by exploiting temporal correlations, the reliability of side information is estimated in a block unit. Then, the location information of the unreliable blocks is provided to the encoder side and thus it enables the encoder to selectively encode the frame difference signal in pixel-domain Wyner-Ziv residual encoder. Experimental results show that the proposed scheme performs better than the DISCOVER scheme as well as the H.264 intra-mode coding scheme.
