Blind image restoration is an approach to estimate both the original image and the point spread function from degraded images,when there is no or little knowledge of the point spread function of the degraded process. In this paper,the main algorithms of blind image restoration are reviewed and classified into four types,according to their theory origins and relationships,and analysis is made for all the types of blind image restoration algorithms and relevant improved algorithms. This will be helpful to better understand the theory of blind image restoration and to restore degraded images.
