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

In recent years researchers have presented a number of new methods for recovering
physiological parameters using just low-cost digital cameras and image processing. The …

Noncontact imaging photoplethysmography (PPG) can provide physiological assessment at
various anatomical locations with no discomfort to the patient. However, most previous …

Heart rate (HR) ranks among the most critical physiological indicators in the human body,
significantly illuminating an individual's state of physical health. Distinguished from …

Imaging photoplethysmography (PPG) is able to capture useful physiological data remotely
from a wide range of anatomical locations. Recent imaging PPG studies have concentrated …

Photoplethysmography (PPG) devices are widely used for monitoring cardiovascular
function. However, these devices require skin contact, which restricts their use to at-rest …

In this paper, we present a novel photoplethysmographic device that operates remotely, ie
not in contact with the skin. The device allows for real time measurements of heart rate with …

Photoplethysmography (PPG) is a noninvasive optical technique for detecting microvascular
blood volume changes in tissues. Its ease of use, low cost and convenience make it an …

We present a new method of formation photoplethysmographic images with high spatial
resolution from video recordings of a living body in the reflection geometry. The method …

Vital signs such as heart rate, respiratory rate, blood pressure, body temperature, and
oxygen saturation are essential for early detection of any related significant illness. Many of …
