Blind Deblurring Based on Sigmoid Function [PDF]

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

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.

Application of Blind Deblurring Reconstruction Technique to SPECT Imaging [PDF]

open access: yesInternational Journal of Biomedical Imaging, 2007
An SPECT image can be approximated as the convolution of the ground truth spatial radioactivity with the system point spread function (PSF). The PSF of an SPECT system is determined by the combined effect of several factors, including the gamma camera ...

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 ...

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.

Recovering Blurred Images to Recognize Field Information

open access: yesProceedings, 2022
This paper introduces a new computational approach for fast deblurring non-blind imaging. The method implementation reveals how to solve image deblurring integrals with arbitrary kernels using the Theory of Hypernumbers. The method is applicable for real-

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.

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 ...

An image defocus deblurring method based on gradient difference of boundary neighborhood

open access: yesVirtual Reality & Intelligent Hardware, 2023
Background: For static scenes with multiple depth layers, the existing defocused image deblurring methods have the problems of edge ringing artifacts or insufficient deblurring degree due to inaccurate estimation of blur amount, In addition, the prior ...
