Measuring vital signs such as heart rate using a camera has the potential to enable better health monitoring for subjects at risk and as such enhance their quality of life. Applications could include driver monitoring via in-dash camera, critical function operator monitoring at work, or remote health monitoring via a webcam. For such a system to be feasible however, it needs to be work well in realistic...
Proliferation of wearable devices and the “quantified self” behavior creates massive amounts of data acquired from physiological sensors. Unfortunately this vast amount of data is to date largely untapped for clinical purposes because of low data reliability caused by issues such as contact noise and motion artifacts. One important physiological signal is ECG and one of its important features is the...
Analysis of Heart Rate Variability (HRV) is an active area of research in the engineering and the medical communities. Current studies use medical-grade ECG signals, from a limited number of available databases. On the other hand, the trend for physiological measurements is towards less obtrusive, wearable devices. It is therefore of interest to apply HRV analysis to signals from such wearable sensors,...
