Abstract
The noise model is one of the most important
aspects influencing the coding performance of Distributed
Video Coding. This paper proposes a novel noise model for
Transform Domain Wyner-Ziv (TDWZ) video coding by using
clustering of DCT blocks. The clustering algorithm takes
advantage of the residual information of all frequency bands,
iteratively classifies blocks into different categories and
estimates the noise parameter in each category. The
experimental results show that the coding performance of the
proposed cluster level noise model is competitive with state-ofthe-
art coefficient level noise modelling. Furthermore, the
proposed cluster level noise model is adaptively combined with
a coefficient level noise model in this paper to robustly improve
coding performance of TDWZ video codec up to 1.24 dB (by
Bjøntegaard metric) compared to the DISCOVER TDWZ
video codec.
