An Open Framework for Remote-PPG Methods and Their Assessment

IEEE Access, 2020
This paper presents a comprehensive framework for studying methods of pulse rate estimation relying on remote photoplethysmography (rPPG). There has been a remarkable development of rPPG techniques in recent years, and the publication of several surveys ...

Remote photoplethysmography (rPPG) to measure heart rate and blood oxygenation levels using colour, infrared and depth data from real home environments

, 2023
Heart Rate (HR) and Blood Oxygenation Level (SPO₂) are physiological signs that are critically important measurements in the assessment of emergent ill-health. These typically require physical contact and blood tests that are often prohibitive for people

Remote Photoplethysmography-Based Deepfake Detection: A Systematic Review

IEEE Access
The rapid evolution of deepfake generation techniques based on Generative Adversarial Networks (GANs), autoencoders, and diffusion models has produced highly realistic facial forgeries that increasingly evade visual artifact detectors.
