Convex MRF potential functions
A general definition of convex potential functions is given for discontinuity-preserving MRF restoration models. This gives a class of Bayesian (image) MRF models which satisfy several desirable analytical and computational properties for regularization of ill-posed problems. The relationship between potential functions in MRF models and their discontinuity-preserving property is discussed and an important guideline is derived for devising potential functions in MRF models to be adaptive to discontinuities.
