  title={Illumination Invariant Face Recognition Using Thermal Infrared Imagery},
  author={Diego A. Socolinsky and Lawrence B. Wolff and Joshua D. Neuheisel and Christopher K. Eveland},
A key problem for face recognition has been accurate identification under variable illumination conditions. Conventional video cameras sense reflected light so that image grayvalues are a product of both intrinsic skin reflectivity and external incident illumination, thus obfuscating the intrinsic reflectivity of skin. Thermal emission from skin, on the other hand, is an intrinsic measurement that can be isolated from external illumination. We examine the invariance of Long-Wave InfraRed (LWIR… CONTINUE READING
