Abstract: To solve the problems of deterministic blind restoration, like the special phenomena of ringing and insufficient suppression noise, the high-order P-Laplace operator is introduced into the classical total variation restoration methods. Firstly, shock filter is used to predict the clear edges of images, and then deal with edge and internal smooth region of images in different forms respectively according to changing rules of the natural image pixels. Finally, it restores the images by split Bregman iteration and alternating minimization algorithm. The experimental results show that the improved algorithm proposed in the paper can alleviate the ringing phenomenon, protect edge information and ameliorate the effects of image restoration compared to a number of blind restoration algorithms in recent years.
