Imaging Photoplethysmography: Signal Waveform Analysis [PDF]
2019 10th IEEE International Conference on Intelligent Data Acquisition and Advanced Computing Systems: Technology and Applications (IDAACS), 2019 Imaging photoplethysmography (iPPG) is used to remotely measure the blood volume pulse using a camera. Traditionally, it has been employed to estimate heart and respiratory rates, and recently blood pressure and oxygen saturation. Biomedical engineering researchers have become increasingly interested in iPPG because of its several advantages as comfort,

Fatigue Driving Detection Method Based on IPPG Technology
Promet (Zagreb), 2023 Physiological signal index can accurately reflect the degree of fatigue, but the contact detection method will greatly affect the driver's driving. This paper presents a non-contact method for detecting tired driving. It uses cameras and other devices to

On the Vector Space in Photoplethysmography Imaging [PDF]
2019 IEEE/CVF International Conference on Computer Vision Workshop (ICCVW), 2019 We study the vector space of visible wavelength intensities from face videos widely used as input features in Photoplethysmography Imaging (PPGI). Based upon theoretical principles of group invariance in the Euclidean space, we derive a change of the topology where the corresponding distance between successive measurements is defined as geodesic on a ...

Intraoperative Imaging of Cortical Blood Flow by Camera-Based Photoplethysmography at Green Light
Applied Sciences, 2020 Intraoperative evaluation of blood perfusion in the brain cortex is an important but hitherto unresolved problem. Our aim was to demonstrate the feasibility of cerebral microcirculation assessment during open brain surgery by using camera-based ...

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 ...

A Review of Atrial Fibrillation Detection Methods as a Service [PDF]
, 2020 Atrial Fibrillation (AF) is a common heart arrhythmia that often goes undetected, and even if it is detected, managing the condition may be challenging. In this paper, we review how the RR interval and Electrocardiogram (ECG) signals, incorporated into a
