Abstract: In this paper, a blind image deblurring method based on weighted mean curvature regularization is proposed, which combines explicit and implicit salient edge selection strategies, that is, taking weighted mean curvature regularization term as implicit edge selection term, and using mutually guided image filtering to achieve explicit edge selection. The weighted mean curvature regularization method is used to remove the unfavorable structure and the details in the intermediate potential image, and preserve the salient edges, which is conducive to blur kernel estimation. In addition, the half-quadratic splitting method and weighted mean curvature filter are used for algorithm optimization to approximate the model effectively. Experiments show that the proposed method is superior to other blind deblurring methods on both benchmark datasets and real-world blurry images.
