Performance Evaluation of rPPG Approaches with and without the Region-of-Interest Localization Step

Applied Sciences, 2021
Traditionally, the first step in physiological measurements based on remote photoplethysmography (rPPG) is localizing the region of interest (ROI) that contains a desired pulsatile information. Recently, approaches that do not require this step have been

Color-Distortion Filtering for Remote Photoplethysmography

2017 12th IEEE International Conference on Automatic Face & Gesture Recognition (FG 2017), 2017
This paper introduces a powerful filtering method that exploits the physiological and optical properties of skin reflections to improve the performance of remote photoplethysmography (rPPG). Based on the fact that the pulsatile and non-pulsatile (e.g., intensity and specular changes) components have different reflection-spectra in a multi-wavelength ...

Monte Carlo Analysis of Optical Interactions in Reflectance and Transmittance Finger Photoplethysmography [PDF]

, 2019
Photoplethysmography (PPG) is a non-invasive photometric technique that measures the volume changes in arterial blood. Recent studies have reported limitations in developing and optimising PPG-based sensing technologies due to unavailability of the ...

Photoplethysmography based remote health monitoring system [PDF]

2013 IEEE International Conference on Smart Instrumentation, Measurement and Applications (ICSIMA), 2013
One of the world's most leading killer diseases is the cardiovascular disease, which accounts for 16.7 million deaths annually. Out of the total population in the world, about 22 million people run the risk of sudden heart failure. However, saving the lives of cardiac patients can be improved by the emergency monitoring so that the initiation of ...

Motion limitations of non-contact photoplethysmography due to the optical and topological properties of skin [PDF]

, 2016
Non-contact photoplethysmography (PPG) provides multiple benefits over in-contact methods, but is not as tolerant to motion due to the lack of mechanical coupling between the subject and sensor.

Estimating Blood Pressure from Photoplethysmogram Signal and Demographic Features using Machine Learning Techniques

, 2020
Hypertension is a potentially unsafe health ailment, which can be indicated directly from the Blood pressure (BP). Hypertension always leads to other health complications. Continuous monitoring of BP is very important; however, cuff-based BP measurements

Cuff-Less Methods for Blood Pressure Telemonitoring. [PDF]

, 2019
Blood pressure telemonitoring (BPT) is a telemedicine strategy that uses a patient\u27s self-measured blood pressure (BP) and transmits this information to healthcare providers, typically over the internet.

Improvements in Remote Cardiopulmonary Measurement Using a Five Band Digital Camera [PDF]

, 2014
Remote measurement of the blood volume pulse via photoplethysmography (PPG) using digital cameras and ambient light has great potential for healthcare and affective computing. However, traditional RGB cameras have limited frequency resolution. We present

Facial Kinship Verification from remote photoplethysmography

, 2023
Facial Kinship Verification (FKV) aims at automatically determining whether two subjects have a kinship relation based on human faces. It has potential applications in finding missing children and social media analysis. Traditional FKV faces challenges as it is vulnerable to spoof attacks and raises privacy issues.
