Quasi-newton Approach to Nonnegative Image Restorations
Image restoration, or deblurring, is the process of attempting to correct for degradation in a recorded image. Typically the blurring system is assumed to be linear and spatially invariant, and fast Fourier transform based schemes result in eecient computational image restoration methods. However, real images have properties that cannot always be handled by linear methods. In particular, an ima...

متن کاملA Quasi-Newton Approach to Nonsmooth Convex Optimization A Quasi-Newton Approach to Nonsmooth Convex Optimization
We extend the well-known BFGS quasi-Newton method and its limited-memory variant (LBFGS) to the optimization of nonsmooth convex objectives. This is done in a rigorous fashion by generalizing three components of BFGS to subdifferentials: The local quadratic model, the identification of a descent direction, and the Wolfe line search conditions. We apply the resulting subLBFGS algorithm to L2-reg...
متن کاملA New Projected Quasi-Newton Approach for the Nonnegative Least Squares Problem
Constrained least squares estimation lies at the heart of many applications in fields as diverse as statistics, psychometrics, signal processing, or even machine learning. Nonnegativity requirements on the model variables are amongst the simplest constraints that arise naturally, and the corresponding least-squares problem is called Nonnegative Least Squares or NNLS. In this paper we present a ...
متن کاملLarge-Scale Optimization Techniques for Nonnegative Image Restorations
We describe an optimization method for large-scale nonnegative regularization. The method is an interiorpoint iteration that requires the solution of a large-scale and possibly ill-conditioned parameterized trust-region subproblem at each step. The method relies on recently developed techniques for the large-scale trust-region subproblem. We present preliminary numerical results on image restor...
