IPPG Signals and Corresponding Blood Pressure Data Extracted from CN-BP and VV-Small Datasets

CN-BP is the publicly available CN-BP dataset in our previous work. It contains facial videos and blood pressure data of 43 Asians. The videos have a resolution of 1920x1080 and a frame rate of 30 FPS.

Polygenic scores for executive functioning as predictors of performance improvements after repeated testing in major psychiatric disorders

Scientific Reports
Executive Functions (EF) control goal-oriented behaviors and are disrupted in patients with psychiatric disorders (PPD). Repeated EF testing in clinical practice and research aims to evaluate disease progression and treatment efficacy.

In vivo imaging and modeling of artery blood pressure wave and interaction with light in time domain

, 2023
Artery blood flow driven by pressure wave is essential for human life. The long-term research goal is to establish a foundation for future translation of the imaging photoplethysmography (iPPG) method into applications such as extraction of vital health ...

Motion Resistant Image-Photoplethysmography Based on Spectral Peak Tracking Algorithm

IEEE Access, 2018
Medical fields have seen increasing attention being given to image based heart rate measurement in recent years. One of the major limitations is motion artifacts of subject's head. Although there have been many studies focusing on signal extraction using

Evaluation of a video-based measure of driver heart rate

, 2014
Internal driver events such as emotional arousal do not consistently elicit observable behaviors. However, heart rate (HR) offers promise as a surrogate measure for predicting these states in drivers.

Time-Series U-Net With Recurrence for Noise-Robust Imaging Photoplethysmography

IEEE Access
Remote estimation of vital signs enables health monitoring for situations in which contact-based devices are either not available, too intrusive, or too expensive. In this paper, we present a modular pipeline for pulse signal estimation from video of the

Imaging photoplethysmography: towards effective physiological measurements [PDF]

, 2011
Since its conception decades ago, Photoplethysmography (PPG) the non-invasive opto-electronic technique that measures arterial pulsations in-vivo has proven its worth by achieving and maintaining its rank as a compulsory standard of patient ...

A systematic approach to improving the signal processing and illumination in imaging photoplethysmography

, 2019
The utilisation of opto-electrical techniques in biomedical monitoring has become increasingly widespread, largely due to its non-invasive nature and the relatively low requirements for the hardware setup.

Real-Time Respiratory Rate Estimation using Imaging Photoplethysmography Inter-Beat Intervals [PDF]

Imaging photoplethysmography (iPPG) has emerged as a contactless heart-rate monitoring technique. As the respiratory activity modulates the heart rate, we investigate the accuracy of iPPG in conveying the inter-beat variation due to the respiratory ...
