Constructing high-order functional connectivity network based on central moment features for diagnosis of autism spectrum disorder [PDF]

open access: yesPeerJ, 2021
The sliding-window-based dynamic functional connectivity network (D-FCN) has been becoming an increasingly useful tool for understanding the changes of brain connectivity patterns and the association of neurological diseases with these dynamic variations.

Eyes Recognition System Using Central Moment Features [PDF]

open access: yesEngineering and Technology Journal, 2011
Central moment is widely used in pattern recognition because of their discrimination power and robustness. For eye recognition these moments can also be normalized so that the moments are also size invariant.

Feature Extraction for Moving Targets Based on the Statistical Characteristics of Echo Amplitude with the L-Band Fully Polarimetric Radar

open access: yesRemote Sensing, 2022
Non-imaging radar can achieve the detection and localization of moving targets, but it faces difficulties in the classification of targets. Aiming for the application of moving target classification by low/medium resolution non-imaging radar, this paper ...

Central modulation of cardiac baroreflex moment‐to‐moment sensitivity during treadmill exercise in conscious cats

open access: yesPhysiological Reports, 2022
It remains undetermined whether the cardiac component of the entire arterial baroreflex is blunted even at the onset of low‐intensity exercise. We sought to examine the moment‐to‐moment sensitivity of the cardiac baroreflex during walking at different ...
