This paper presents a image restoration method based on knife-edge PSF (Point Spread Function) estimation and Edge-preserving Regularization Model for the China-Brazil Earth Resource Satellite-2 (CBERS-2) image. Based on typical image area, the knife-edge method is used to obtain edge spread function and point spread function. The Huber-Markov prior model is employed to establish the regularization model, and the steepest descent method is used to solve the restored image. Experimental results show that this method is superior to the traditional recovery methods when applied to CBERS-2 images, both form vision and quantitative aspects.
