A Simple Local Minimal Intensity Prior and an Improved Algorithm for Blind Image Deblurring

نویسندگان

چکیده

Blind image deblurring is a long standing challenging problem in processing and low-level vision. Recently, sophisticated priors such as dark channel prior, extreme local maximum gradient have shown promising effectiveness. However, these methods are computationally expensive. Meanwhile, since involved subproblems cannot be solved explicitly, approximate solution commonly used, which limits the best exploitation of their capability. To address problems, this work firstly proposes simplified sparsity prior minimal pixels, namely patch-wise pixels (PMP). The PMP clear images much more sparse than that blurred ones, hence very effective discriminating between images. Then, novel algorithm designed to efficiently exploit deblurring. new flexibly imposes inducing on under MAP framework rather directly uses half quadratic splitting algorithm. By this, it avoids non-rigorous approximation existing algorithms, while being efficient. Extensive experiments demonstrate proposed can achieve better practical stability compared with state-of-the-arts. In terms quality, robustness computational efficiency, superior Code for reproducing results method available at https://github.com/FWen/deblur-pmp.git.

Learning a Discriminative Prior for Blind Image Deblurring

We present an effective blind image deblurring method based on a data-driven discriminative prior. Our work is motivated by the fact that a good image prior should favor clear images over blurred images. In this work, we formulate the image prior as a binary classifier which can be achieved by a deep convolutional neural network (CNN). The learned prior is able to distinguish whether an input i...

Kernel Optimization for Blind Motion Deblurring with Image Edge Prior

Image motion deblurring with unknown blur kernel is an ill-posed problem. This paper proposes a blind motion deblurring approach that solves blur kernel and the latent image robustly. For kernel optimization, an edge mask is used as an image prior to improve kernel update, then an edge selection mask is adopted to improve image update. In addition, an alternative iterative method is introduced ...

An improved non-blind image deblurring methods based on FoEs

Traditional non-blind image deblurring algorithms always use maximum a posterior(MAP). MAP estimates involving natural image priors can reduce the ripples effectively in contrast to maximum likelihood(ML). However, they have been found lacking in terms of restoration performance. Based on this issue, we utilize MAP with KL penalty to replace traditional MAP. We develop an image reconstruction a...
