A generalized matrix Krylov subspace method for TV regularization
This paper presents an efficient algorithm to solve total variation (TV) regularizations of images contaminated by a both blur and noise. The unconstrained structure of the problem suggests that one can solve a constrained optimization problem by transforming the original unconstrained minimization problem to an equivalent constrained minimization one. An augmented Lagrangian method is develope...
متن کاملEigenvalue Perturbation and Generalized Krylov Subspace Method
In this paper, we study the computational aspect of eigenvalue perturbation theory. In previous research, high order perturbation terms were often derived from Taylor series expansion. Computations based on such an approach can be both unstable and highly complicated. We present here with an approach based on the diierential formulation of perturbation theory where the high order perturbation c...
متن کاملTikhonov regularization based on generalized Krylov subspace methods
We consider Tikhonov regularization of large linear discrete ill-posed problems with a regularization operator of general form and present an iterative scheme based on a generalized Krylov subspace method. This method simultaneously reduces both the matrix of the linear discrete ill-posed problem and the regularization operator. The reduced problem so obtained may be solved, e.g., with the aid ...
متن کاملA Generalized Krylov Subspace Method for ℓp-ℓq Minimization
This paper presents a new efficient approach for the solution of the lp-lq minimization problem based on the application of successive orthogonal projections onto generalized Krylov subspaces of increasing dimension. The subspaces are generated according to the iteratively reweighted least-squares strategy for the approximation of lp/lq-norms by weighted l2-norms. Computed image restoration exa...
متن کاملA Krylov subspace method for option pricing
We consider the pricing of financial contracts that are based on two or three underlyings and are modelled using time dependent linear parabolic partial differential equations (PDEs). To provide accurate and efficient numerical approximations to the financial contract’s value, we decompose the numerical solution into two parts. The first part involves the spatial discretization, using finite di...
