Definition
Infrared face recognition systems use infrared sensors to measure the thermal radiation emitted in the infrared spectrum range.
One of the major problems of traditional face recognition systems is constant performance under uncontrolled environments, and especially under extreme variations in illumination conditions, e.g., operating in total darkness or full daylight in an open area surveillance scenario. Such problems may be alleviated using infrared (IR) images for face recognition. Unlike conventional visual cameras, which measure the electromagnetic energy in the visible spectrum range, infrared sensors measure the thermal radiation emitted in the infrared spectrum range (0.7–0.14 μm) [1]. Thermal images of the human face represent patterns caused from superficial blood vessels up to 4 cm below the skin surface, which transport warm blood throughout the body and heat the skin just above them by an average of 0.1°C [2]. The vein and tissue structure of an individual is...
