The attractive structures in human perception often correspond to objects of interest and have great practical importance. Therefore, extracting the attractive structures from images is a fundamental problem in many image analysis tasks. We in this letter propose a novel nonuniform method to maintain the attractive structures for image analysis while removing meaningless details. Our nonuniform method...
Partial differential equations (PDEs) have been used to formulate image processing for several decades. Generally, a PDE system consists of two components: the governing equation and the boundary condition. In most previous work, both of them are generally designed by people using mathematical skills. However, in real world visual analysis tasks, such predefined and fixed-form PDEs may not be able...
Blind image deblurring, i.e., estimating a blur kernel from a single input blurred image is a severely ill-posed problem. In this paper, we show how to effectively apply low rank prior to blind image deblurring and then propose a new algorithm which combines salient edges and low rank prior. Salient edges provide reliable edge information for kernel estimation, while low rank prior provides data-authentic...
