On Using rPPG Signals for DeepFake Detection: A Cautionary Note

open access: yes, 2023
An experimental analysis is proposed concerning the use of physiological signals, specifically remote Photoplethysmography (rPPG), as a potential means for detecting Deepfakes (DF). The study investigates the effects of different variables, such as video compression and face swap quality, on rPPG information extracted from both original and forged ...

Effectiveness of Remote PPG Construction Methods: A Preliminary Analysis

open access: yesBioengineering, 2022
The contactless recording of a photoplethysmography (PPG) signal with a Red-Green-Blue (RGB) camera is known as remote photoplethysmography (rPPG).

Remote photoplethysmography with constrained ICA using periodicity and chrominance constraints

open access: yesBioMedical Engineering OnLine, 2018
Background Remote photoplethysmography (rPPG) has been in the forefront recently for measuring cardiac pulse rates from live or recorded videos. It finds advantages in scenarios requiring remote monitoring, such as medicine and fitness, where contact ...

Contactless facial video recording with deep learning models for the detection of atrial fibrillation

open access: yesScientific Reports, 2022
Atrial fibrillation (AF) is often asymptomatic and paroxysmal. Screening and monitoring are needed especially for people at high risk. This study sought to use camera-based remote photoplethysmography (rPPG) with a deep convolutional neural network (DCNN)

A Reproducible Study on Remote Heart Rate Measurement [PDF]

open access: yes, 2017
This paper studies the problem of reproducible research in remote photoplethysmography (rPPG). Most of the work published in this domain is assessed on privately-owned databases, making it difficult to evaluate proposed algorithms in a standard and ...

Cord pilot trial, comparing alternative policies for timing of cord clamping before 32 weeks gestation: follow-up for women up to one year. [PDF]

open access: yes, 2019
BACKGROUND: The Cord Pilot Trial compared two alternative policies for cord clamping at very preterm birth at eight UK maternity units: clamping after at least 2 min and immediate neonatal care (if needed) with cord intact, or clamping within 20 s and ...

Validity and Reliability of the Heart Rate Matching Task: A Novel Measure of Heart Rate Estimation

open access: yesPsychophysiology, Volume 63, Issue 4, April 2026.
ABSTRACT Sensing and monitoring changes in our heart rate is a key aspect of interoception. We introduce and test the construct validity of the Heart Rate Matching task (HRM), a novel, fast and accessible task designed to assess the ability to estimate heart rate, in both remote (i.e., online) and in‐lab settings.

Photoplethysmography for Measuring Cognitive Load in XR Environments: A Systematic Review

open access: yesAdvanced Sensor Research, Volume 5, Issue 3, March 2026.
ABSTRACT Photoplethysmography (PPG) is a low‐cost, low‐power biosensing technology with growing applications in education, particularly for monitoring cognitive load in eXtended Reality (XR) learning environments. Measuring cognitive load is critical for preventing overload and optimising immersive learning, yet existing approaches such as self‐reports
