Over the last few years, the contactless acquisition of cardiovascular parameters using
cameras has gained immense attention. The technique provides an optical means to …

Hypertension is one of the most prevalent diseases and is often called the “silent killer”
because there are usually no early symptoms. Hypertension is also associated with multiple …

This paper presents an overview of the state of the art of three different fields with the shared
characteristics of making use of a network of sensors, with the possible application of …

Remote pulse rate measurement from facial video has gained particular attention over the
last few years. Research exhibits significant advancements and demonstrates that common …

Objectives: Camera-based vital sign estimation allows the contactless assessment of
important physiological parameters. Seminal contributions were made in the 1930s, 1980s …

Objective. Evaluate a method for the estimation of the nocturnal systolic blood pressure
(SBP) dip from 24 h blood pressure trends using a wrist-worn photoplethysmography (PPG) …

Photoplethysmographic Imaging (PPGI) allows the determination of pulse rate variability
from sequential beat-to-beat intervals (BBI) and pulse wave velocity from spatially resolved …

Noninvasive, convenient, and reliable cardiovascular health assessment using pervasive
healthcare applications can help in preventing cardiovascular diseases (CVDs). This study …

The contactless estimation of vital signs using conventional color cameras and ambient light
can be affected by motion artifacts and changes in ambient light. On both these problems, a …

This study investigates the beat-to-beat relationships among Pulse Transit Times (PTTs) and
