Noise-Adaptive Non-Blind Image Deblurring [PDF]

open access: yesSensors, 2022
This work addresses the problem of non-blind image deblurring for arbitrary input noise. The problem arises in the context of sensors with strong chromatic aberrations, as well as in standard cameras, in low-light and high-speed scenarios.

Effective Alternating Direction Optimization Methods for Sparsity-Constrained Blind Image Deblurring [PDF]

open access: yesSensors, 2017
Single-image blind deblurring for imaging sensors in the Internet of Things (IoT) is a challenging ill-conditioned inverse problem, which requires regularization techniques to stabilize the image restoration process.

Overview of Blind Deblurring Methods for Single Image [PDF]

open access: yesJisuanji kexue yu tansuo, 2022
Image deblurring has been a research hotspot in computer vision and image processing for a long time. The motion blur or focus blur image caused by camera jitter, object motion or defocus will seriously affect the use and follow-up processing of the ...

Gradient-wise search strategy for blind image deblurring [PDF]

open access: yesMATEC Web of Conferences, 2022
Blind image deblurring is a long-standing challenging problem to improve the sharpness of an image as a prerequisite step. Many iterative methods are widely used for the deblurring image, but care must be taken to ensure that the methods have fast ...

Blind Deblurring Based on a Single Luminance Channel and L1-Norm

open access: yesIEEE Access, 2021
To improve the image quality of the deblurring results restored by existing blind deblurring method, an effective image blind deblurring method based on a single channel and L1-norm is proposed for the blurry images.

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

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.

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 ...

MedDeblur: Medical Image Deblurring with Residual Dense Spatial-Asymmetric Attention

open access: yesMathematics, 2022
Medical image acquisition devices are susceptible to producing blurry images due to respiratory and patient movement. Despite having a notable impact on such blind-motion deblurring, medical image deblurring is still underexposed.

COMBINED PATCH-WISE MINIMAL-MAXIMAL PIXELS REGULARIZATION FOR DEBLURRING [PDF]

open access: yesISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2020
Deblurring is a vital image pre-processing procedure to improve the quality of images. It is a classical ill-posed problem. A new blind deblurring method based on image sparsity prior is proposed here.
