Facial skin temperature is closely related to the underlying blood vessels; thus by obtaining a thermal map of the human face we can also extract the pattern of the blood vessels just below the skin. Thermal Infrared Imaging has many applications in different scientific, engineering, research, and medical areas. This paper presents preliminary findings using thermal infrared imaging for the detection of the human face vasculature network at the skin surface and the generation of thermal facial signatures. The thermal infrared images were then analyzed using digital image processing techniques to enhance and detect the facial vasculature network of the volunteers and generate a thermal facial signature for each volunteer. We further present a comprehensive performance analysis of multiple appearance-based face recognition methodologies, on visible and thermal infrared imagery. The effect of illumination conditions on recognition performance is emphasized, as it underlines the relative advantage of radio metrically calibrated thermal imagery for face recognition.
