A self‐supervised scheme for ground roll suppression

open access: yesGeophysical Prospecting, Volume 72, Issue 7, Page 2580-2598, September 2024.
Abstract In recent years, self‐supervised procedures have advanced the field of seismic noise attenuation, due to not requiring a massive amount of clean labelled data in the training stage, an unobtainable requirement for seismic data. However, current self‐supervised methods usually suppress simple noise types, such as random and trace‐wise noise ...

In vivo T2 measurements of the fetal brain using single‐shot fast spin echo sequences

open access: yesMagnetic Resonance in Medicine, Volume 92, Issue 2, Page 715-729, August 2024.
Abstract Purpose We propose a quantitative framework for motion‐corrected T2 fetal brain measurements in vivo and validate the single‐shot fast spin echo (SS‐FSE) sequence to perform these measurements. Methods Stacks of two‐dimensional SS‐FSE slices are acquired with different echo times (TE) and motion‐corrected with slice‐to‐volume reconstruction ...

Irregular shearlet frames

open access: yes, 2009
Die Themen dieser Dissertation sind die notwendigen und die hinreichenden Bedingungen fuer die Frameeigenschaft in L^2(R^2) bei irregulren Shearlet-Systemen. Zu diesem Zweck fuehren wir die Konzepte der Dichte irregulaerer Shearlet-Systeme ein, die als geeignete Ansaetze zum Erkennen der Verbindung zwischen der Geometrie diskreter, mit den irregulren ...

An infrared and visible image fusion network based on multi‐scale feature cascades and non‐local attention

open access: yesIET Image Processing, Volume 18, Issue 8, Page 2114-2125, 19 June 2024.
This paper introduces a novel infrared and visible image fusion network to address the limitations of auto‐encoder fusion networks. In the designed network, the encoder employs a multi‐branch cascade structure with convolution kernels of different sizes to extract multi‐scale features, and the fusion layer incorporates a non‐local attention module ...

Deep learning‐based methods for detecting defects in cast iron parts and surfaces

open access: yesIET Image Processing, Volume 18, Issue 1, Page 47-58, 10 January 2024.
First, this article used multiple data augmentation methods to alleviate the problem of small sample size in casting datasets. Second, attention mechanism was introduced. Finally, a novel feature fusion layer structure was adopted to improve the original network model.

Shearlets on Bounded Domains [PDF]

open access: yes, 2011
Shearlet systems have so far been only considered as a means to analyze $L^2$-functions defined on $\R^2$, which exhibit curvilinear singularities. However, in applications such as image processing or numerical solvers of partial differential equations the function to be analyzed or efficiently encoded is typically defined on a non-rectangular shaped ...

mBCCf: Multilevel Breast Cancer Classification Framework Using Radiomic Features

open access: yesInternational Journal of Intelligent Systems, Volume 2024, Issue 1, 2024.
Breast cancer characterization remains a significant and challenging issue in contemporary medicine. Accurately distinguishing between malignant and benign breast lesions is crucial for effective diagnosis and treatment. The anatomical structure of malignant breast ultrasound images is more chaotic than that of benign images due to disease pathologies.
