Abstract: Aiming for low-complexity encoding, distributed video
coders still fail to achieve the performance of current industrial
standards for video coding. One of most important
problems in this area is the accurate modeling of the correlation
between the predicted signal and the original video.
In our previous work we showed that exploiting the quantization
distortion can significantly improve the accuracy of
a correlation estimator. In this paper we describe how the
quantization distortion can be exploited purely at the decoder
side without any performance penalty when compared to an
encoder-aided system. As a result, the proposed correlation
estimator delivers state-of-the-art modeling accuracy while
neatly fitting the low-encoder-complexity characteristic of
distributed video coding.
