Image priors based on products have been recognized
to offer many advantages because they allow simultaneous enforcement of multiple constraints. However, they are inconvenient for
Bayesian inferenc...
A spatio-spectral hybridization for edge preservation and noisy image restoration via local parametric mixtures and Lagrangian relaxation
Edge preserving smoother Semiparametric mixture model Partition of unity MISE Variational optimization Thin Plate Splines Spectral embedding Local template mod-els Multiple hypothesis testing.
