In this paper, the issue of blind image restoration is considered by using 2-D Great Common Divisor (GCD) extraction approach. A precise extraction algorithm of 2-D GCD is proposed. Since no high order ill-posed equation is needed, calculation complexity and noise robustness for the algorithm are improved. Simulation result shows that the proposed algorithm is able to provide a better performance than traditional algorithm.
