Parameter estimation for an H.264-based distributed video coder
In this paper we present a statistical model used to select coding parameters for a mixed resolution Wyner-Ziv framework implemented using the H.264/AVC standard. This paper extends the results of a previous work for the H.263+ case to the H.264/AVC coder, since the parameters need to be recalculated for the H.264 case. The proposed correlation estimation mechanism guides the parameter choice process, and also yields the statistical model used for decoding. This mechanism is proposed based on extracting edge information and residual error rate in co-located blocks from the low resolution base layer that is available at both ends.
