Research progressing during the last decade focuses more on non-contact based systems
to monitor Heart Rate (HR) which are simple, low-cost and comfortable to use. Most of the …

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 …

Heart Rate Variability (HRV) signal analysis provides a quantitative marker of the Autonomic
Nervous System (ANS) function. A wristband-type wireless photoplethysmographic (PPG) …

Heart rate variability (HRV) has become a marker for various health and disease conditions.
Photoplethysmography (PPG) sensors integrated in wearable devices such as smart …

As a reliable indicator for individual's healthiness conditions, heart rate (HR) has been
widely considered and used. Imaging photoplethysmography (iPPG) is recently highlighted …

Video-based photoplethysmography (vPPG) enables remote and contactless detection of
the peripheral pulse of blood flow. This provides a potential mean to extract heart rate (HR) …

Remote Photoplethysmography (rPPG) is a fast-growing technique of vital sign estimation by
analyzing video of a person. Several major phenomena affecting rPPG signals were studied …

Existing video plethysmography methods use standard red-green-blue (sRGB) video
recordings of the facial region to estimate heart pulse rate without making contact with the …

Wearables are being increasingly used to monitor heart rate (HR). However, their
usefulness for analyzing continuous HR in research or at clinical level is questionable. The …

Background Photoplethysmography is a noninvasive and low-cost method to remotely and
continuously track vital signs. The Oura Ring is a compact photoplethysmography-based …
