A Survey on Extracting Physiological Measurements from Thermal Images

Multiple techniques are used to extract physiological signals from the human body. These signals provide a reliable method to identify the physical and mental state of a person at any given point in time. However, these techniques require contact and cooperation of the individual as well as human effort for connecting the devices and collecting the needed measurement. Moreover, these methods can be invasive, time-consuming, and infeasible in many cases. Recent efforts have been made in order to find alternatives to extract these measurements using non-contact and efficient techniques. In this paper we provide a survey that explores different approaches for extracting vital signs from thermal images as well as review applications that could potentially leverage these techniques.
