It is well known that changes in skin color due to\nblood flow can be captured using conventional cameras. One of the main\nlimitations of methods that rely on this principle is the need of an\nillumination source. Moreover, they have to be able to operate under different\nlight conditions. One way to avoid these constraints is using infrared cameras,\nallowing the monitoring of iHR under low light conditions. In this work, we\npresent a simple, principled signal extraction method that recovers the iHR\nfrom infrared face videos. We tested the procedure on 7 participants, for whom\nwe recorded an electrocardiogram simultaneously with their infrared face video.\nWe checked that the recovered signal matched the ground truth iHR, showing that\ninfrared is a promising alternative to conventional video imaging for heart\nrate monitoring, especially in low light conditions.
