Background Advancements in wearable technology have provided practitioners and
researchers with the ability to conveniently measure various health and/or fitness indices …

Background Heart rate fluctuates beat-by-beat asymmetrically which is known as heart rate
asymmetry (HRA). It is challenging to assess HRA robustly based on short-term heartbeat …

In recent years, research about monitoring vital signs by smartphones grows significantly.
There are some special sensors like Electrocardiogram (ECG) and Photoplethysmo-graphic …

Camera-based measurement of the blood volume pulse via non-contact, imaging
photoplethysmography is a very popular approach for measuring pulse rate using a remote …

Non-contact, long-term monitoring human heart rate is of great importance to home health
care. Recent studies show that Photoplethysmography (PPG) can provide a means of heart …

Wearables are a ubiquitous trend in both commercial and academic settings as they easily
enable tracking and monitoring of physiological parameters such as heart rate (HR) and …

This paper presents algorithms to improve the estimation of heart rate (HR) and heart rate
variability (HRV) from smartphone video. The remote photoplethysmogram (rPPG) signals …

In this paper, we propose a novel heart rate (HR) estimation method using simultaneously
recorded RGB and near-infrared (NIR) face videos. The key idea of our method is to …

The challenge of heart rate monitoring based on wrist photoplethysmography (PPG) during
heavy exercise is addressed. PPG is susceptible to motion artefacts, which have to be …

Remote photoplethysmography (PPG) estimates vital signs by measuring changes in the
reflected light from the human skin. Compared to traditional PPG techniques, remote PPG …
