Non-contact heart rate and heart rate variability measurements have applications in
healthcare and affective computing. Recently, a system utilizing a five-band camera …

Heart rate variability (HRV) is a useful clinical tool for autonomic function assessment and
cardiovascular diseases diagnosis. It is traditionally calculated from a dedicated medical …

Remote photoplethysmography (rPPG) gains recent great interest due to its potential in
contactless heart rate measurement using consumer-level cameras. This paper presents a …

Recently, the camera-based photoplethysmography (PPG) techniques have been proposed
for heart rate measurement due to the contactless and low-cost features. However, the …

Peak-to-peak intervals in Photoplethysmography (PPG) can be used for heart rate variability
(HRV) estimation if the PPG is collected from a healthy person at rest. Many factors, such as …

Heart rate variability (HRV), extracted from an electrocardiogram, is known to be a
noninvasive indicator reflecting the dynamic interplay between perturbations to …

Photoplethysmographic signals are useful for heart rate variability analysis in practical
ambulatory applications. While reducing the sampling rate of signals is an important …

A measurement method of heart rate and heart rate variability (HRV) based on smartphone
has been developed and validated. The method is based on photoplethysmography (PPG) …

The aim of this paper is to present a smartphone based system for real-time pulse-to-pulse
(PP) interval time series acquisition by frame-to-frame camera image processing. The …

In the field of healthcare, a fundamental research topic includes the development of a vital
signs monitoring system that allows people to monitor their health state so that they can …
