which is the NIM potential vector associated with clique types
, respectively. We observe that the NIM potential
vector is in a quadratic form. The quadratic assumption is widely
used to model images in numerous problems [12] and is called
the Gaussian MRF (GMRF) model. GMRF models are suitable
for describing smooth images with a large number of intensity
levels. Furthermore, under thisGMRFmodel, (19) can be solved
more easily due to the fact that the summation over configuration
space in (17) changes to infinite integration in product
space. Hence, the analytical solution for (19) can be derived.
Using the GMRF model [14], [15], we can rewrite (20) as
