| Abstract: |
| This paper is devoted to study image denoising and deblurring problems. By using regularization technology and Krylov subspace method, a hybrid regularization LSQR algorithm is proposed. The experimental results show that the algorithm can effectively improve the ill-posedness of the problem and obtain the restored image with high fidelity. |
