| Abstract: | We present a remote sensing restoration method based on knife-edge PSF estimation and edge-preserving regularization model.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 recovery model.The steepest descent method is used to solve the restored image.Experimental results show that this method is superior to traditional recovering methods. |
