Exploiting Spatial Redundancy of Image Sensor for Motion Robust rPPG [PDF]
IEEE Transactions on Biomedical Engineering, 2015 Remote photoplethysmography (rPPG) techniques can measure cardiac activity by detecting pulse-induced color variations on human skin using an RGB camera. State-of-the-art rPPG methods are sensitive to subject body motions (e.g., motion-induced color distortions). This study proposes a novel framework to improve the motion robustness of rPPG.

Real-Time Webcam Heart-Rate and Variability Estimation with Clean Ground Truth for Evaluation
Applied Sciences, 2020 Remote photo-plethysmography (rPPG) uses a camera to estimate a person’s heart rate (HR). Similar to how heart rate can provide useful information about a person’s vital signs, insights about the underlying physio/psychological conditions can be obtained

Addiction à l'alcool, objet concret et régulation des éprouvés internes [PDF]
, 2004 International audienceClinical work with alcoholics led us to examine intra-psychic tensions that existed prior to alcoholism and to foresee using them as a strategy for controlling—external, specific, and illusory—their “indescribable” internal feelings.

Heart Rate Measurement Based on 3D Central Difference Convolution with Attention Mechanism
Sensors, 2022 Remote photoplethysmography (rPPG) is a video-based non-contact heart rate measurement technology. It is a fact that most existing rPPG methods fail to deal with the spatiotemporal features of the video, which is significant for the extraction of the ...

Video pulse rate variability analysis in stationary and motion conditions [PDF]
, 2018 Background: In the last few years, some studies have measured heart rate (HR) or heart rate variability (HRV) parameters using a video camera. This technique focuses on the measurement of the small changes in skin colour caused by blood perfusion.
