Photoplethysmography (PPG) is a simple optical technique used to detect blood volume
changes in the micro-vascular bed of tissue in order to track the heartbeat. Smart-phone …

Continuous measurement of heart rate variability (HRV) in the short and ultra-short-term
using wearable devices allows monitoring of physiological status and prevention of …

Remote photoplethysmography (rPPG) allows contactless monitoring of human cardiac
activity through a video camera. In this study, we assessed the accuracy and precision for …

In this paper we present a novel health monitoring method by estimating the heart rate and
respiratory rate using an RGB camera. The heart rate and the respiratory rate are estimated …

Remote photoplethysmography (rPPG) provides a non-contact method for measuring blood
volume changes. In this study, we compared rPPG signals obtained from video cameras with …

Continuous measurement of physiological functions, like heart rate (HR) and heart rate
variability (HRV), using commercially available wearable sensors provides the prospects of …

We compared classic ECG-derived versus a mobile approach to heart rate variability (HRV)
measurement. Methods & results 29 young adult healthy volunteers underwent a …

Heart rate (HR) estimation and monitoring is of great importance to determine a person's
physiological and mental status. Recently, it has been demonstrated that HR can be …

Heart Rate Variability (HRV) has become an important risk assessment tool when
diagnosing illnesses related to heart health. HRV is typically measured with an …

As a non-invasive approach to monitor heart rate (HR), the photoplethysmography (PPG)
signal provides a simple and accurate measurement in silence. However, difficulties are …
