The inherent restrictions of human body images acquired at visible spectrum hinder the performance of person recognition systems built using that kind of information (e.g. scene artifacts under varying illumination conditions). One promising approach for dealing with those limitations is using images acquired out of the visible spectrum. This paper reviews some of the existing human body imaging technologies working beyond the visible spectrum (X-ray, Infrared, Millimeter and Submillimeter Wave imaging technologies). The pros and cons of each technology and their biometric applications are presented, with special attention to Millimeter and Submillimeter Wave imaging.
