Approximate Schur Complement Preconditioners for Half-Quadratic Image Restoration With Zero Boundary Conditions
In this paper, the additive half-quadratic image restoration problem with zero boundary conditions is investigated. The Newton method is used to solve this problem and a structured linear system needs solving at each step. In order to accelerate this process, we have proposed a preconditioning metho...
