Dynamics Reconstruction of Remote Photoplethysmography

2022
Photoplethysmography based medical devices are widely used for cardiovascular status monitoring. In recent years, many algorithms have been developed to achieve cardiovascular monitoring results comparable to the medical device from remote photoplethysmography (rPPG).

Remote Photoplethysmography measurement using constrained ICA

2017 E-Health and Bioengineering Conference (EHB), 2017
Remote Photoplethysmography (rPPG) is a technique that consists in estimating physiological parameters such as heart rate from live or recorded video sequences taken by conventional camera or even webcams. This technique is increasingly used in many application fields thanks to its simplicity and affordability. The basic idea is that the arterial blood

ROI Selection for Remote Photoplethysmography

2013
Camera-based remote photoplethysmography (rPPG) is a technique that can be used to measure vital signs contactlessly. In order to optimize the extraction of photoplethysmographic signals from video sequences, we investigate the spatial dependence of the photoplethysmographic signal.
