Blur2Sharp: A GAN-Based Model for Document Image Deblurring
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 ...

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

A Blur Restoration Algorithm Based on L0 Regularization [PDF]
Aiming at the motion blur,a new blind deblurring algorithm is proposed,which is based on the L0 regularization restraints and the prior knowledge of natural image gradient distribution to obtain the real motion kernel.In the proposed methods,T-smooth ...

Hyper-Laplacian Regularized Non-Local Low-Rank Prior for Blind Image Deblurring
Blind deblurring of single image is a challenging image restoration problem. Recent various image priors have been successfully explored to solve this ill-posed problem. In this paper, based on the non-local self-similarity, we propose a novel method for

Blind image deblurring method based on
Aiming at the problem of ringing artifacts existing in the edge of image in traditional blind image deblurring methods, l1/l2 regularization-based blind image deblurring method is proposed. The latent image is constrained by l1/l2 regularization, and the

Comparative Analysis of Non-Blind Deblurring Methods for Noisy Blurred Images
Image blurring refers to the degradation of an image wherein the image's overall sharpness decreases. Image blurring is caused by several factors. Additionally, during the image acquisition process, noise may get added to the image.

REGULARIZATION BY INEXACT KRYLOV METHODS WITH APPLICATIONS TO BLIND DEBLURRING [PDF]
This paper is concerned with the regularization of large-scale discrete inverse problems by means of inexact Krylov methods. Specifically, we derive two new inexact Krylov methods that can be efficiently applied to unregularized or Tikhonov-regularized ...
