An algorithm for image restoration with mixed noise using total variation regularization

Abstract

We present here an effective scheme for image denoising based on total variation regularization. The proposedscheme allows to efficiently remove Poisson noise as well as Gaussian noise simultaneously with the help of a newkind of data fidelity term, suitable for the mixed Poisson–Gaussian noise model. The results show that the algorithmcorresponding to our new scheme outperforms the existing methods for mixed Poisson–Gaussian noise removal.
