%X Based on Generalized Minimal RESidual(GMRES) method and regularization technique,a new image restoration method is presented.The method is based on the Arnoldi process,which yields a sequence of smaller least squares problems to approximate the original ill-posed problem.Truncated Singular Value Decomposition(TSVD) regularization is used to solve these least squares problems stably.According the characters of image restoration,L-curve criterion is modified while selecting iteration in TSVD method.Numerical results illustrate good restoration effect.
