Efficient preconditioning strategies for accelerating GMRES in block-structured nonlinear systems for image deblurring.
We propose an efficient preconditioning strategy to accelerate the convergence of Krylov subspace methods, specifically for solving complex nonlinear systems with a block five-by-five structure, commonly found in cell-centered finite difference discretizations for image deblurring using mean curvatu...
