Motion-Robust Atrial Fibrillation Detection Based on Remote-Photoplethysmography
IEEE Journal of Biomedical and Health Informatics, 2023Atrial fibrillation (AF) has been proven highly correlated to stroke; more than 43 million people suffer from AF worldwide. However, most of these patients are unaware of their disease. There is no convenient tool by which to conduct a comprehensive screening to identify asymptomatic AF patients.

Remote photoplethysmography for assessment of oral mucosa
Clinical and Preclinical Optical Diagnostics II, 2019The present study is devoted to the assessment of oral mucosa perfusion using remote photoplethysmography (rPPG) technique. The alterations of mucosal perfusion were evoked by regional infiltration anesthesia containing adrenaline. Simple rPPG setup comprising white LED light source, video camera and narrowband optical filter (CWL=540nm), are able to ...

Motion artifacts suppression for remote imaging photoplethysmography
2014 19th International Conference on Digital Signal Processing, 2014Remote imaging photoplethysmography (RIPPG) is able to access human vital signs without physical contact. However most of the conventional RIPPG approaches are susceptive to motions of subjects or camera. Overcoming motion artifacts presents one of the most challenging problems.

Remote Photoplethysmography Enhancement with Machine Leaning Methods
2019 IEEE International Conference on Systems, Man and Cybernetics (SMC), 2019Driver’s physiological state is highly correlated to the traffic safety. An affordable and convenient way to monitor driver’s physiological state is remote Photoplethysmography (rPPG). Earlier algorithms achieved high accuracy on measuring rPPG signals in stationary case.

Remote photoplethysmography based on reflected light angle estimation
Physiological MeasurementAbstract Objective. In previous studies, the factors affecting the accuracy of imaging photoplethysmography (iPPG) heart rate (HR) measurement have been focused on the light intensity, facial reflection angle, and motion artifacts. However, the factor of specularly reflected light has not been studied in detail.

Towards Collecting Big Data for Remote Photoplethysmography
2021Remote photoplethysmography (rPPG) is a technique for non-contact estimation of human vital signs in video. It enriches knowledge about human state and makes interpretations of actions in human-computer interaction more accurate. An approach to distributed collection of rPPG dataset is proposed along with a central hub where data is accumulated as ...

Block-based adaptive ROI for remote photoplethysmography
Multimedia Tools and Applications, 2017Remote photoplethysmography (rPPG) can achieve contactless human vital signs monitoring, but its signal quality is limited by the remote operation nature. In practical applications, improving the rPPG signal quality becomes an essential task. As a remote imaging technique, rPPG utilizes a camera to capture a video of a skin area, especially the facial ...
