We propose a novel variational framework for image restoration based on the assumption that noise is additive and white. In particular, the proposed variational model uses total variation regularization and forces the resemblance of the residue image to a white noise realization by imposing constraints in the frequency domain. The whiteness constraint constitutes the key novelty behind our approach. The restored image is efficiently computed by the constrained minimization of an energy… CONTINUE READING
