Abstract: The paper addresses an essential problem in distributed
video coding (DVC) which is modeling and estimation of
the correlation channel. Current works assume the
distribution of the correlation noise to be independent
from the realization of the side-information. The paper
demonstrates that this assumption is inaccurate and
proposes a novel model which depends on the realization
of the side-information. The proposed model is
experimentally validated showing remarkable accuracy
over conventional models. Driven by the sideinformation-
dependency of the proposed model, a novel
technique for estimating the correlation channel in video
at the decoder is introduced. The proposed technique is
incorporated into a unidirectional spatial-domain DVC
system achieving similar performance compared to the
state-of-the-art transform-domain DVC at a much lower
encoding complexity
