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 …

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 …

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 …

As a smartphone is becoming very popular and its performance is being improved fast, a
smartphone shows its potential as a low-cost physiological measurement solution which is …

Mobile health monitors allow patients to leave the hospital and engage in normal activity,
uploading physiological data only periodically. Most existing system use fixed gateways to …

This work compares several fiducial points to detect the arrival of a new pulse in a
photoplethysmographic signal using the built-in camera of smartphones or a …

Heart rate variability (HRV) analysis is well established as a quantitative predictor of clinical
cardiac events. To provide reliable assessment of HRV in mobile settings, short duration …

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 …

Heart Beat Rate calculation has traditionally been conducted using specialized hardware
most commonly in the form of pulse oximeters or Electrocardiogram devices. Even though …

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