Abstract: The W-GCV method is one of the iterative methods used to solve a large scale standard form of the Tikhonov regularization, but it is also necessary for solving the general form of the Tikhonov regularization. This paper proposes a new solver, called GKB-GCV, which is an extension of the W-GCV by using the GSVD. Numerical results are presented to show the usefulness of the GKB-GCV method in large scale ill-posed problems.
Keywords: GKB, W-GCV, Tikhonov regularization, large scale ill-posed problem, Image resolution.
