Non-contact, automated cardiac pulse measurements using video imaging and blind source separation.
TL;DR: This is the first demonstration of a low-cost accurate video-based method for contact-free heart rate measurements that is automated, motion-tolerant and capable of performing concomitant measurements on more than one person at a time.

Robust Pulse Rate From Chrominance-Based rPPG
Gerard De Haan,Vincent Jeanne +1 more
TL;DR: This work presents an analysis of the motion problem, from which far superior chrominance-based methods emerge, and shows remote photoplethysmography methods to perform in 92% good agreement with contact PPG, with RMSE and standard deviation both a factor of 2 better than BSS- based methods.

Photoplethysmography Revisited: From Contact to Noncontact, From Point to Imaging
Yu Sun,Nitish V. Thakor +1 more
TL;DR: This study presents an overview of the wide range of IPPG systems currently being introduced along with examples of their application in various physiological assessments and believes that the widespread acceptance ofIPPG is happening, and it will dramatically accelerate the promotion of this healthcare model in the near future.
Journal ArticleDOI
Smart health monitoring systems: an overview of design and modeling.
TL;DR: The main aim is to review current state of the art monitoring systems and to perform extensive and an in-depth analysis of the findings in the area of smart health monitoring systems.
Journal ArticleDOI
Improved motion robustness of remote-PPG by using the blood volume pulse signature
TL;DR: In this paper, the authors show that the different absorption spectra of arterial blood and bloodless skin cause the variations to occur along a very specific vector in a normalized RGB-space.

Ambulatory system for human motion analysis using a kinematic sensor: monitoring of daily physical activity in the elderly
TL;DR: The ambulatory system showed a very high accuracy (> 99%) in identifying the 62 transfers or rolling out of bed, as well as 144 different posture changes to the back, ventral, right and left sides, in both first and second studies.

Microwave life-detection systems for searching human subjects under earthquake rubble or behind barrier
TL;DR: A new sensitive microwave life-detection system which can be used to locate human subjects buried earthquake rubble or hidden behind various barriers has been constructed and tested extensively.

TL;DR: In this paper, Chest wall and lung volume estimation by optical reflectance motion analysis is presented. But the method is not suitable for the analysis of lung tissue. And it cannot be used for lung cancer diagnosis.

Age-related changes in the characteristics of the photoplethysmographic pulse shape at various body sites.
John F. Allen,Alan Murray +1 more
TL;DR: The overall age-related changes in multi-site PPG pulse shape characteristics at the ear, finger and toe sites have been demonstrated and quantified and age-matched normal ranges must be considered when evaluating pulses from patients with possible vascular disease.

A health monitoring system for elderly people living alone.
TL;DR: A health monitoring system for elderly people living alone by placing infrared sensors in each room of their homes that reduced anxiety for both the elderly subjects living alone and their family members.
