Adaptive-neighborhood image deblurring

Journal of Electronic Imaging, 1994
A new technique is presented for the restoration of images degraded by a linear, shift-invariant blurring point-spread function in the presence of additive white Gaussian noise. The algorithm uses overlapping variable-size, variable-shape adaptive neighborhoods (ANs) to define stationary regions in the input image and obtains a spectral estimate of the

DC-Deblur: A Dilated Convolutional Network for Single Image Deblurring

2021
Single image deblurring is a significant and challenging task in image processing vision and machine learning. Convolutional Neural Network (CNN) based models for deblurring often have a complex structure and a considerable number of parameters compared with those for other image restoration tasks such as image denoising, dehazing and super-resolution.

Deblurring Multispectral Laparoscopic Images

2014
Multispectral imaging is an optical modality that can provide real-time in vivo information about tissue characteristics and function through signal sensitivity to chromophores in the tissue. In this paper, we present a deblurring strategy that enables imaging of dynamic tissues at wavelengths where the required acquisition time can cause significant ...

PSF estimation for image deblurring

CVGIP: Graphical Models and Image Processing, 1991
Abstract This paper addresses the problem of estimating the point spread function (PSF) of a spatially invariant linear system through which an image has been blurred. This is done by searching for specific features of the original image, such as sharp edge elements or microtexture, from which the blur effect can be identified and the PSF estimated ...
