Blind Deblurring Based on Sigmoid Function

open access: yesSensors, 2021
Blind image deblurring, also known as blind image deconvolution, is a long-standing challenge in the field of image processing and low-level vision. To restore a clear version of a severely degraded image, this paper proposes a blind deblurring algorithm

Deblurring Images [PDF]

open access: yesMicroscopy Today, 1998
Abstract If you are an optical microscopist, chances are you have sometimes wished for a way to increase the depth of focus of your images. In this article I describe a method that does this using a simple combination of functions built into most image processing software - so it will not cost you very much to try, The method, however ...

A Single Image Deblurring Approach Based on a Fractional Order Dark Channel Prior

open access: yesInternational Journal of Applied Mathematics and Computer Science, 2022
The dark channel prior has been successfully applied to solve the blind deblurring problem on different scene images. Since the dark channel of the blurry-noise image is similar to that of the corresponding clear image, the sparsity of the dark channel ...

Edge-aware deep image deblurring

open access: yesNeurocomputing, 2022
Image deblurring is a fundamental and challenging low-level vision problem. Previous vision research indicates that edge structure in natural scenes is one of the most important factors to estimate the abilities of human visual perception. In this paper, we resort to human visual demands of sharp edges and propose a two-phase edge-aware deep network to

Blind Image Deblurring Based on Local Edges Selection

open access: yesApplied Sciences, 2019
The edges of images are less sparse when images become blurred. Selecting effective image edges is a vital step in image deblurring, which can help us to build image deblurring models more accurately.

A Motion Deblur Method Based on Multi-Scale High Frequency Residual Image Learning

open access: yesIEEE Access, 2020
Non-uniform blind deblurring of dynamic scenes has always been a challenging problem in image processing because of the diverse of blurring sources. Traditional methods based on energy minimization cannot make accurate kernel estimation. It leads to that

Infrared Image Deblurring Based on Generative Adversarial Networks

open access: yesInternational Journal of Optics, 2021
Blind deblurring of a single infrared image is a challenging computer vision problem. Because the blur is not only caused by the motion of different objects but also by the relative motion and jitter of cameras, there is a change of scene depth.

An improved nonlocal sparse regularization-based image deblurring via novel similarity criteria

open access: yesInternational Journal of Advanced Robotic Systems, 2018
Image deblurring is a challenging problem in image processing, which aims to reconstruct an original high-quality image from its blurred measurement caused by various factors, for example, imperfect focusing caused by the imaging system or different ...
