A retraced spiral strategy with semi‐automatic deblurring for volumetric thermometry

open access: yesMagnetic Resonance in Medicine, Volume 94, Issue 4, Page 1432-1444, October 2025.
Abstract Purpose To develop a 3D MRI‐thermometry technique for transcranial MR‐guided focused ultrasound (MRgFUS). Methods A stack of retraced in‐out (RIO) spirals was incorporated into a 3D, RF‐spoiled, gradient recalled echo (GRE) sequence with a minimized energy deblurring strategy. Bloch simulations examined isochromat precession during RIO readout

Learning to Extract a Video Sequence from a Single Motion-Blurred Image

open access: yes, 2018
We present a method to extract a video sequence from a single motion-blurred image. Motion-blurred images are the result of an averaging process, where instant frames are accumulated over time during the exposure of the sensor.

An Accelerated Spectral CG‐Type Projection Method With Restart Strategy for Nonlinear Monotone Equations and Applications in Compressed Sensing

open access: yesNumerical Linear Algebra with Applications, Volume 32, Issue 5, October 2025.
ABSTRACT In this study, we present an accelerated spectral conjugate gradient‐type projection method to solve the system of nonlinear monotone equations. Compared to traditional methods for solving such equations, this method utilizes three‐step successive information to produce inertial iterates.

Hyper-Laplacian Regularized Non-Local Low-Rank Prior for Blind Image Deblurring

open access: yesIEEE Access, 2020
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

Distributed Deblurring of Large Images of Wide Field-Of-View

open access: yes, 2017
Image deblurring is an economic way to reduce certain degradations (blur and noise) in acquired images. Thus, it has become essential tool in high resolution imaging in many applications, e.g., astronomy, microscopy or computational photography.
