In 2008, the Sensors Exploitation Research Group at the Air Force
Institute of Technology began using spectral properties of skin for
the detection and classi cation of humans. Since then a
multispectral skin detection system was developed to exploit the
optical properties of human skin at wavelengths in the visible and
near infrared region of the electromagnetic spectrum. A rules-based
detector, analyzing an image spectrally, currently bases its skin
pixel selection criteria on a di use skin reflectance model.
However, when observing skin in direct view of the sun, a glint of
light o skin is common and indicates specularity. The areas of skin
with a high degree of specular reflectance, results in
misdetections. We show that skin is characterized by di use and
specular reflectance, with both components dependent on the scene
con guration. While we cannot always rely on the person to directly
face the camera or have constant illumination conditions, it is
important to have flexibility with the rules-based detector as the
scene changes. Our research better characterizes skin reflectance
as a function of source and detector angular locations to improve
on the rules-based detector.
