Rick Chartrand and Valentina Staneva, "A quasi-Newton method for total variation regularization of images corrupted by non-Gaussian noise", To appear in IET Image Process., 2008

Abstract

Our aim is to obtain efficient algorithms for image regularization optimized for removing different types of noise. To accomplish this, we combine total variation regularization with a noise-specific way to measure the fidelity between the noisy image and the reconstruction. We find a minimum of the resulting functional with a quasi-Newton method, which converges faster than the common method of gradient descent. As examples we consider Poisson noise and impulse noise. We prove convergence of the algorithm for a large class of fidelity terms.
