Stereoscopic video deblurring transformer

open access: yesScientific Reports
Stereoscopic cameras, such as those in mobile phones and various recent intelligent systems, are becoming increasingly common. Multiple variables can impact the stereo video quality, e.g., blur distortion due to camera/object movement.

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 ...

Deblurring gaussian blur [PDF]

open access: yesComputer Vision, Graphics, and Image Processing, 1986
Summary: Gaussian blur, or convolution against a Gaussian kernel, is a common model for image and signal degradation. In general, the process of reversing Gaussian blur is unstable, and cannot be represented as a convolution filter in the spatial domain.

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.

CORE-Deblur: Parallel MRI Reconstruction by Deblurring using compressed sensing [PDF]

open access: yesMagnetic Resonance Imaging, 2020
In this work we introduce a new method that combines Parallel MRI and Compressed Sensing (CS) for accelerated image reconstruction from subsampled k-space data. The method first computes a convolved image, which gives the convolution between a user-defined kernel and the unknown MR image, and then reconstructs the image by CS-based image deblurring, in

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.

Improved Classification of Blurred Images with Deep-Learning Networks Using Lucy-Richardson-Rosen Algorithm

open access: yesPhotonics, 2023
Pattern recognition techniques form the heart of most, if not all, incoherent linear shift-invariant systems. When an object is recorded using a camera, the object information is sampled by the point spread function (PSF) of the system, replacing every ...

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 ...
