| Abstract: | The blocked Gmres algorithm has certain superiority in dealing with the large systems of linear equations, a new algorithm to combine the regularization algorithm with blocked Gmres algorithm in image restoration filed is proposed. The algorithm considers the time and space complexity in image restora In the numerical simulation, different methods are compared, the results show that the method can significantly improves the quality of image restoration. |
