A Hybrid Regularized GMRES(m) Method for Image Restoration
图像恢复的正则化混合GMRES(m)方法

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.
