Edge-based blur kernel estimation using patch priors [PDF]

open access: yesIEEE International Conference on Computational Photography (ICCP), 2013
Blind image deconvolution, i.e., estimating a blur kernel k and a latent image x from an input blurred image y, is a severely ill-posed problem. In this paper we introduce a new patch-based strategy for kernel estimation in blind deconvolution. Our approach estimates a “trusted” subset of x by imposing a patch prior specifically tailored towards ...

Combining Motion Compensation with Spatiotemporal Constraint for Video Deblurring

open access: yesSensors, 2018
We propose a video deblurring method by combining motion compensation with spatiotemporal constraint for restoring blurry video caused by camera shake.

Blur kernel estimation using normalized color-line priors [PDF]

open access: yes2015 IEEE Conference on Computer Vision and Pattern Recognition (CVPR), 2015
This paper proposes a single-image blur kernel estimation algorithm that utilizes the normalized color-line prior to restore sharp edges without altering edge structures or enhancing noise. The proposed prior is derived from the color-line model, which has been successfully applied to non-blind deconvolution and many computer vision problems.

Understanding Kernel Size in Blind Deconvolution

open access: yes, 2019
Most blind deconvolution methods usually pre-define a large kernel size to guarantee the support domain. Blur kernel estimation error is likely to be introduced, yielding severe artifacts in deblurring results.

Joint Blind Motion Deblurring and Depth Estimation of Light Field

open access: yes, 2018
Removing camera motion blur from a single light field is a challenging task since it is highly ill-posed inverse problem. The problem becomes even worse when blur kernel varies spatially due to scene depth variation and high-order camera motion.

Deep Eyes: Binocular Depth-from-Focus on Focal Stack Pairs

open access: yes, 2020
Human visual system relies on both binocular stereo cues and monocular focusness cues to gain effective 3D perception. In computer vision, the two problems are traditionally solved in separate tracks.

Fast and easy blind deblurring using an inverse filter and PROBE

open access: yes, 2017
PROBE (Progressive Removal of Blur Residual) is a recursive framework for blind deblurring. Using the elementary modified inverse filter at its core, PROBE's experimental performance meets or exceeds the state of the art, both visually and quantitatively.

Deep Self-Learning Network for Adaptive Pansharpening

open access: yesRemote Sensing, 2019
Deep learning (DL)-based paradigms have recently made many advances in image pansharpening. However, most of the existing methods directly downscale the multispectral (MSI) and panchromatic (PAN) images with default blur kernel to construct the training ...
