“…To integrate colour-based and motion-based approaches, Weidi et al [121] introduced two fusion techniques, the mean method and the ratio of variations method, to extract HR using an industrial camera. They reported that a colour-based method is more reliable than a motion-based method.…”

Techniques for noncontact measurement of vital signs using camera imaging technologies have been attracting increasing attention. For noncontact physiological assessments, computer vision-based methods appear to be an advantageous approach that could be robust, hygienic, reliable, safe, cost effective and suitable for long distance and long-term monitoring. In addition, video techniques allow measurements from multiple individuals opportunistically and simultaneously in groups. This paper aims to explore the progress of the technology from controlled clinical scenarios with fixed monitoring installations and controlled lighting, towards uncontrolled environments, crowds and moving sensor platforms. We focus on the diversity of applications and scenarios being studied in this topic. From this review it emerges that automatic multiple regions of interest (ROIs) selection, removal of noise artefacts caused by both illumination variations and motion artefacts, simultaneous multiple person monitoring, long distance detection, multi-camera fusion and accepted publicly available datasets are topics that still require research to enable the technology to mature into many real-world applications.

“…As shown in [13], intensity-and motion-based approaches have advantages and disadvantages. Intensitybased methods are capable of overcoming motion artefact in the video, whereas motion-based methods are unable to deal with large motions.…”

“…By making use of this knowledge, intensity-based methods can be applied when less intensity artefacts occur and, analogue to this, the motion-based methods when less motion artefacts occur. This was implemented in a ratio-based method proposed in [13].…”

Abstract:The remote determination of vital parameters can contribute to the field of ambient assisted living (AAL) to face the challenges of a steadily ageing society. In this study, we examined the possibility to remotely measure the four vital parameters heart rate, respiration rate, oxygen saturation and blood pressure in AAL environments. For this, we evaluated the state of the art, implementations and concepts. While, the determination of heart and respiration rate is ready for usage, further attention has to be paid to the determination of oxygen saturation and blood pressure.
