【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.更多还原
