Robust Image Restoration for Motion Blur of Image Sensors

open access: yesSensors, 2016
Blind image restoration algorithms for motion blur have been deeply researched in the past years. Although great progress has been made, blurred images containing large blur and rich, small details still cannot be restored perfectly.

Hyperspectral Image Reconstruction Based on Blur–Kernel–Prior and Spatial–Spectral Attention

open access: yesRemote Sensing
Given the problem of spatial detail loss and spectral feature degradation in hyperspectral images (HSIs) characterized as blur, often caused by noise during image acquisition, and methods of removing blur noise designed on HSIs being insufficient, we ...

Blind Text Image Deblurring Algorithm Based on Multi-Scale Fusion and Sparse Priors

open access: yesIEEE Access, 2023
The goal of blind text image deblurring is to obtain a clean text image from the given blurry text image without knowing the blur kernel. Sparsity-based methods have been shown their effectiveness in various blind text image deblurring models.

Super Resolution with Kernel Estimation and Dual Attention Mechanism

open access: yesInformation, 2020
Convolutional Neural Networks (CNN) have led to promising performance in super-resolution (SR). Most SR methods are trained and evaluated on predefined blur kernel datasets (e.g., bicubic).

High energy flash X‐ray image restoration using region extrema and kernel optimization

open access: yesIET Image Processing, 2021
The quality of high energy flash X‐ray images is crucial to the high‐precision diagnosis of object density. High energy flash X‐ray radiography is susceptible to the system blur, which usually causes the poor quality of static images. In response to this,

A New Super Resolution Framework Based on Multi-Task Learning for Remote Sensing Images

open access: yesSensors, 2021
Super-resolution (SR) algorithms based on deep learning have dominated in various tasks, including medical imaging, street view surveillance and face recognition. In the remote sensing field, most of the current SR methods utilize the low-resolution (LR)

BLUR KERNEL’S EFFECT ON PERFORMANCE OF SINGLE-FRAME SUPER-RESOLUTION ALGORITHMS FOR SPATIALLY ENHANCING HYPERION AND PRISMA DATA [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2022
Single-frame super-resolution (SFSR) achieves the goal of generating a high-resolution image from a single low-resolution input in a three-step process, namely, noise removal, up-sampling and deblurring.
