Background The cardiac parameters, such as heart rate (HR) and heart rate variability
(HRV), are very important physiological data for daily healthcare. Recently, the camera …

Remote photoplethysmography (RPPG) is a technique to measure the physiological signs
(such as Heart Rate) remotely. Compared with the conventional photoplethysmography …

Camera-based remote photoplethysmography (rPPG) is a low-cost and casual non-contact
heart rate measurement method suitable for telemedicine. Several factors affect the …

Significance: Non-contact, camera-based heart rate variability estimation is desirable in
numerous applications, including medical, automotive, and entertainment. Unfortunately …

Video recordings of finger tips made using a smartphone camera contain a pulsatile
component caused by the cardiac pulse equivalent to that present in a …

The purpose of this study is to evaluate the effectiveness of heartbeat error and
compensation methods on heart rate variability (HRV) with mobile and wearable sensor …

Introduction: This study investigates the accuracy of a heart rate (HR) measurement
algorithm applied to a pulse wave. This was based on video signals recorded with a …

A telemetry system for the measurement of heart rate variability (HRV) has been developed
with a low-cost manufacturing process and a low-power consumption design. All the …

Background. Heart rate variability (HRV) provides information about the activity of the
autonomic nervous system. Because of the small amount of data collected, the importance of …

Heart rate variability (HRV) is a measurement of the fluctuation of time between each
heartbeat and reflects the function of the autonomic nervous system. HRV is an important …
