The Brain Health Index: Integrating Vulnerability, Resilience, and Functioning Into a Unified Measure of Cognitive Health and Neurodegenerative Risk [PDF]

open access: yesAlzheimers Dement
Abstract Background The Brain Health Index (BHI) is a comprehensive assessment tool that integrates three key components to create a unified measure of cognitive health: the Vulnerability Index (VI), which assesses both modifiable and non‐modifiable risk factors for cognitive impairment; the Resilience Index (RI), measuring six distinct modifiable ...

Image Separation Based on Nonsubsampled Contourlet(NSCT)

open access: yesInternational Journal on Organic Electronics, 2013
When an image or a document on a paper acquired through scanning, photographing or photocopying, the image on the back page may be show through. This cause a non-linear image mixture and should be resolved through a non-linear source separation. In this paper, we improve a previously introduced method, which suppose two independent images in the same ...

A Novel Partial Discharge Detection Method Based on the Photoelectric Fusion Pattern in GIL

open access: yesEnergies, 2019
Optical detection and ultrahigh frequency (UHF) detection are two significant methods of partial discharge (PD) detection in the gas-insulated transmission lines (GIL), however, there is a phenomenon of signals loss when using two types of detections to ...

A hybrid NSCT domain image watermarking scheme

open access: yesEURASIP Journal on Image and Video Processing, 2017
At present, dealing with the piracy and tampering of images has become a notable challenge, due to the presence of smart mobile gadgets. In this paper, we propose a novel watermarking algorithm based on non-subsampled contourlet transform (NSCT) for improving the security aspects of such images.
