Learning Wavefront Coding for Extended Depth of Field Imaging [PDF]

open access: yes, 2020
Depth of field is an important factor of imaging systems that highly affects the quality of the acquired spatial information. Extended depth of field (EDoF) imaging is a challenging ill-posed problem and has been extensively addressed in the literature ...

A domain translation network with contrastive constraint for unpaired motion image deblurring

open access: yesIET Image Processing, 2023
Most motion deblurring methods require a large amount of paired training data, which is nearly unreachable in practice. To overcome the limitation, a domain translation network with contrastive constraint for unpaired motion image deblurring is proposed.

$L_p$ -Norm-Based Sparse Regularization Model for License Plate Deblurring

open access: yesIEEE Access, 2020
We propose an $L_{p}$ -norm-based sparse regularization model for license plate deblurring, which is motivated by distinctive properties of license plate images. For the blurred images, general deblurring methods may restore a good overall visual effect.

Learning to Deblur

open access: yesIEEE Transactions on Pattern Analysis and Machine Intelligence, 2016
We describe a learning-based approach to blind image deconvolution. It uses a deep layered architecture, parts of which are borrowed from recent work on neural network learning, and parts of which incorporate computations that are specific to image deconvolution.

Learning a Convolutional Neural Network for Non-uniform Motion Blur Removal [PDF]

open access: yes, 2015
In this paper, we address the problem of estimating and removing non-uniform motion blur from a single blurry image. We propose a deep learning approach to predicting the probabilistic distribution of motion blur at the patch level using a convolutional ...

Deep Face Deblurring

open access: yes2017 IEEE Conference on Computer Vision and Pattern Recognition Workshops (CVPRW), 2017
Blind deblurring consists a long studied task, however the outcomes of generic methods are not effective in real world blurred images. Domain-specific methods for deblurring targeted object categories, e.g. text or faces, frequently outperform their generic counterparts, hence they are attracting an increasing amount of attention.

Blur2Sharp: A GAN-Based Model for Document Image Deblurring

open access: yesInternational Journal of Computational Intelligence Systems, 2021
The advances in mobile technology and portable cameras have facilitated enormously the acquisition of text images. However, the blur caused by camera shake or out-of-focus problems may affect the quality of acquired images and their use as input for ...

Wasserstein Generative Adversarial Network Based De-Blurring Using Perceptual Similarity

open access: yesApplied Sciences, 2019
The de-blurring of blurred images is one of the most important image processing methods and it can be used for the preprocessing step in many multimedia and computer vision applications. Recently, de-blurring methods have been performed by neural network

Iterative Blind Deconvolution Algorithm for Deblurring a Single PSP/TSP Image of Rotating Surfaces

open access: yesSensors, 2018
Imaging of pressure-sensitive paint (PSP) for pressure measurement on moving surfaces is problematic due to the movement of the object within the finite exposure time of the imager, resulting in the blurring of the blade edges.
