The convergence of mean field procedures for MRFs [image processing].
Convergence of the mean field equations is analyzed for the Ising model with a nonhomogeneous external field. When beta is small, the equations are a contraction mapping and thereby convergent. When beta is large, however, they can be noncontracting and in this case, contraction is restored by a slight modification of the equations.
