AB -  Image restoration is an ill-posed inverse problem, which has been introduced the regularization 
method to suppress over-amplification. In this paper, we propose to apply the iterative regularization method 
to  the  image  restoration  problem  and  present  a  nested  iterative  method,  called  iterative  conjugate  gradient 
regularization method. Convergence properties are established in detail. Based on [6], we also simultaneously 
determine the regularization parameter based on the restored image at each step. Simulation results show that 
the proposed iterative regularization method is feasible and effective for image restoration.
