A Patient-Invariant Model for Freezing of Gait Detection Aided by Wavelet Decomposition

ICASSP 2021accepted

Freezing of Gait (FoG) is a paroxysmal and devitalizing symptom associated with Parkinson’s disease (PD). Episodes of FoG impedes gait and augments fall propensity, often leading to serious fall-injury. In this paper, we present a method for online detection of FoG using a wearable motion sensor. Th…

Time Series and Morphological Feature Extraction for Classifying Coronary Artery Disease from Photoplethysmogram

ICASSP 2018accepted

In this paper we propose a feature extraction algorithm for classifying Coronary Artery Disease (CAD) patients from Photoplethysmogram (PPG) signals. Several domain-independent features, representing inherent properties of a time series are explored in our study. These are combined with Heart Rate V…
