Support Estimation with Sampling Artifacts and Errors [PDF]

open access: yes2021 IEEE International Symposium on Information Theory (ISIT), 2021
The problem of estimating the support of a distribution is of great importance in many areas of machine learning, computer science, physics and biology. Most of the existing work in this domain has focused on settings that assume perfectly accurate sampling approaches, which is seldom true in practical data science.

Measurement of T1 Mapping in Patients With Cardiac Devices: Off-Resonance Error Extends Beyond Visual Artifact but Can Be Quantified and Corrected

open access: yesFrontiers in Cardiovascular Medicine, 2021
Background: Measurement of myocardial T1 is increasingly incorporated into standard cardiovascular magnetic resonance (CMR) protocols, however accuracy may be reduced in patients with metallic cardiovascular implants.

Sparsity-based method for ring artifact elimination in computed tomography.

open access: yesPLoS ONE, 2022
Ring artifact elimination is one of the popular problems in computed tomography (CT). It appears in the reconstructed image in the form of bright or dark patterns of concentric circles.

Real-Time Artifact Removal System for Surface EMG Processing During Ten-Fold Frequency Electrical Stimulation

open access: yesIEEE Access, 2021
In this paper, three easily implemented hardware algorithms, including the adaptive prediction error filter based on the Gram-Schmidt algorithm (GS-APEF), the least mean square adaptive filter and the comb filter, are extensively investigated for ...

Metal artifact reduction in kV CT images throughout two-step sequential deep convolutional neural networks by combining multi-modal imaging (MARTIAN)

open access: yesScientific Reports, 2022
This work attempted to construct a new metal artifact reduction (MAR) framework in kilo-voltage (kV) computed tomography (CT) images by combining (1) deep learning and (2) multi-modal imaging, defined as MARTIAN (Metal Artifact Reduction throughout Two ...

A point-wise artifact rejection method for estimating transient-evoked otoacoustic emissions and their group delay [PDF]

open access: yesJASA Express Letters, 2022
Due to its low intensity, measurement of transient-evoked otoacoustic emission (TEOAE) requires repeated stimulation. When any acoustic artifact occurs, an entire click interval is typically abandoned.

Noise cancellation in brain waves using a new diffusion normalized least power based algorithm for brain computer interface applications

open access: yesMeasurement: Sensors, 2021
In remote health care monitoring applications, continuous brain signal monitoring is a key task. While recording electroencephalogram (EEG) signals in clinical environments various artifacts like respiration artifact (RA), electromyogram (EMG) or electro
