An improved method for nonstationary signals components extraction based on the ICI rule
(
IEEE
, 2011 , Conference Paper)
This paper proposes an improved adaptive algorithm for components localization and extraction from a noisy multicomponent signal time-frequency distribution (TFD). The algorithm, based on the intersection of confidence ...
Time-Frequency Characterization of Tri-Axial Accelerometer Data for Fetal Movement Detection
(
IEEE
, 2011 , Conference Paper)
Monitoring fetal wellbeing is a significant problem in modern obstetrics. Clinicians have become increasingly aware of the link between fetal activity and its well-being. Using data acquired by accelerometry sensors, we ...
An automatic time-frequency procedure for interference suppression by exploiting their geometrical features
(
IEEE
, 2011 , Conference Paper)
This paper presents an adaptive method for interference suppression in the Wigner-Ville distribution. The structure of the artifacts in the Wigner-Ville distribution has been analyzed to optimally mask the signal Wigner-Ville ...
Image quality metrics based multifocus image fusion
(
IEEE
, 2011 , Conference Paper)
We describe an innovative methodology for block based multifocus
image fusion in the spatial domain. The main idea is
to use blind or no reference blur metrics for image fusion applications.
Two blur quality metrics ...
Accelerometer-based fetal movement detection
(
IEEE
, 2011 , Conference Paper)
Monitoring fetal wellbeing is a compelling problem in modern obstetrics. Clinicians have become increasingly aware of the link between fetal activity (movement), well-being, and later developmental outcome. We have recently ...
Kalman filter-based time-varying cortical connectivity analysis of newborn EEG
(
IEEE
, 2011 , Conference Paper)
Multivariate Granger causality in the timefrequency
domain as a representation of time-varying cortical
connectivity in the brain has been investigated for the adult
case. This is, however, not the case in newborns as ...
Detection of neonatal EEG burst-suppression using a time-frequency approach
(
IEEE
, 2014 , Conference Paper)
In newborn EEG, the presence of burst suppression carries with it a high probability of poor neurodevelopmental outcome. This paper presents a novel method to detect neonatal bust suppression from multichannel EEG using a ...
Classification of fetal movement accelerometry through time-frequency features
(
IEEE
, 2014 , Conference Paper)
This paper presents a time-frequency approach for fetal movement monitoring which is based on classification of accelerometry signals collected from pregnant women's abdomen. Features extracted from time-frequency distribution ...
Wideband radar based fall motion detection for a generic elderly
(
IEEE Computer Society
, 2017 , Conference Paper)
Radar-based automated fall detection systems are considered as an important and emerging technology for elderly assisted living. These radar systems provide non-intrusive sensing capabilities to detect fall events. Various ...
Range-Doppler radar sensor fusion for fall detection
(
Institute of Electrical and Electronics Engineers Inc.
, 2017 , Conference Paper)
Falls are the major cause of accidents in the elderly population. Propelled by their non-intrusive sensing capabilities and robustness to heat and lighting conditions, radar-based automated fall detection systems have ...
