An image defocus deblurring method based on gradient difference of boundary neighborhood

open access: yesVirtual Reality & Intelligent Hardware, 2023
Background: For static scenes with multiple depth layers, the existing defocused image deblurring methods have the problems of edge ringing artifacts or insufficient deblurring degree due to inaccurate estimation of blur amount, In addition, the prior ...

Depiction Fidelity and Specificity in Direct MRI of Collagen: Addressing Signal Decay at the Microsecond Timescale

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Gap‐filled zero echo time (ZTE) acquisitions combined with dedicated short‐T2 hardware enable direct collagen imaging on the timescale of macromolecular (MM) signals, with T2s ˜ 10 μs. However, present methods offer limited depiction fidelity, and their specificity towards MM content is poorly understood. This work presents methodology

Accelerated MR Elastography Using Learned Neural Network Representation

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop a deep‐learning method for achieving fast high‐resolution MR elastography from highly undersampled data without the need for high‐quality training datasets. Methods We first reframed the deep neural network representation as a nonlinear extension of the linear subspace model, then used it to represent and reconstruct MRE ...

A user‐friendly platform for deep‐learning‐based image enhancement in scanning X‐ray microscopy

open access: yesJournal of Synchrotron Radiation, EarlyView.
A graphical user interface is developed for deep‐learning‐based image enhancement in scanning X‐ray microscopy. By incorporating the intensity of the probe and scan parameters, the graphical user interface enables accessible and reproducible super‐resolution and deblurring of scanning X‐ray datasets, supporting improved analysis of X‐ray fluorescence ...

Deep Residual Combiner: A Learned Fusion of Spatial, Temporal, and Multiscale Correlated Pixel Estimates

open access: yesComputer Graphics Forum, EarlyView.
Abstract Correlation‐based rendering techniques continue to advance, and efficiently exploiting correlations between pixel estimates has become increasingly important. The deep combiner framework [BHHM20] allows us to fuse independent and correlated pixel estimates but focuses solely on spatial correlations.

Application of Polynomial Transforms in Image Deblurring

open access: yes, 1989
In this paper, we present an algorithm for deblurring and interpolating digital images. Deblurring is an ill-posed problem, which can be made well-behaved by introducing assumptions about the input image.
