Early detection and location of unexpected events in buried pipelines under unseen conditions using the two‐stream global fusion classifier model

open access: yesComputer-Aided Civil and Infrastructure Engineering, EarlyView.
Abstract Failure of buried pipelines can result in serious impacts, such as explosions, environmental contamination, and economic losses. Early detection and location of unexpected events is crucial to prevent such events. However, conventional monitoring methods exhibit limited generalization performance under varying environmental and operational ...

Solving Inverse Problems with Piecewise Linear Estimators: From Gaussian Mixture Models to Structured Sparsity

open access: yes, 2010
A general framework for solving image inverse problems is introduced in this paper. The approach is based on Gaussian mixture models, estimated via a computationally efficient MAP-EM algorithm. A dual mathematical interpretation of the proposed framework

Deciphering the performance of different surface models for corneal topography

open access: yesOphthalmic and Physiological Optics, EarlyView.
Abstract Purpose To study the performance of different corneal surface models to be used for ray tracing. Models based on geometric surfaces and polynomial fits were compared and the differences discussed. Methods For this simulation study, five characteristic generic surface configurations were generated: (A) perfect biconic, (B) decentred biconic ...

Deep Laplacian Pyramid Networks for Fast and Accurate Super-Resolution

open access: yes, 2017
Convolutional neural networks have recently demonstrated high-quality reconstruction for single-image super-resolution. In this paper, we propose the Laplacian Pyramid Super-Resolution Network (LapSRN) to progressively reconstruct the sub-band residuals ...

X‐ray CT metal artifact reduction using neural attenuation field prior

open access: yesMedical Physics, Volume 52, Issue 7, July 2025.
Abstract Background The presence of metal objects in computed tomography (CT) imaging introduces severe artifacts that degrade image quality and hinder accurate diagnosis. While several deep learning‐based metal artifact reduction (MAR) methods have been proposed, they often exhibit poor performance on unseen data and require large datasets to train ...

Detail-revealing Deep Video Super-resolution

open access: yes, 2017
Previous CNN-based video super-resolution approaches need to align multiple frames to the reference. In this paper, we show that proper frame alignment and motion compensation is crucial for achieving high quality results.

Beacon2Science: Enhancing STEREO/HI Beacon Data With Machine Learning for Efficient CME Tracking

open access: yesSpace Weather, Volume 23, Issue 7, July 2025.
Abstract Observing and forecasting coronal mass ejections (CMEs) in real‐time is crucial due to the strong geomagnetic storms they can generate that can have a potentially damaging effect, for example, on satellites and electrical devices. With its near‐real‐time availability, Solar TErrestrial RElations Observatory‐heliospheric imagers (STEREO/HI ...

Surface Mass Balance Variability Causes Viscoelastic Solid Earth Deformation in the Antarctic Peninsula

open access: yesGeophysical Research Letters, Volume 52, Issue 12, 28 June 2025.
Abstract Present‐day ice‐mass changes in Antarctica typically deform the solid Earth elastically, and this signal needs removing from Global Positioning System (GPS) observations of displacement before they can be used to constrain models of glacial isostatic adjustment.
