This paper presents an adaptive weighting factor spatial NAS -RIF blind image restoration algorithm,the cost function spatial adaptive weighting factor is introduced in the original NAS -RIF algorithm to improve image restoration realistic and smooth.The experiment results show that the improved algorithm can improve the signal to noise ratio improvement gain 2.39db,and the detail and clarity of the restored image have improved to some extent.
