| 1. A detection system comprising:
a first detector array for providing a first image having a field-of-view of a scene in a lower reflective infrared band;
a second detector array for providing a second image having the field-of-view of the scene in an upper reflective infrared
band;
a third detector array for providing a third image having the field-of-view of the scene in a visible band;
a subtractive mechanism, connected to the first, second and third detector arrays, for determining the differences of intensities
of elements of the first and second images and forming a fourth image of elements having the differences of intensities and
having the field-of-view;
a thresholder, connected to the subtractive mechanism, for nulling the elements of the fourth image having differences of
intensities that do not meet a certain threshold intensity value;
a feature selector, connected to the thresholder, for finding facial features in the fourth image and detecting a face with
the features;
a framer, connected to the feature selector, for placing a frame around the face in the fourth image;
a first integrator, connected to the framer, for inserting the frame that surrounds the face in the first image; and
a second integrator, connected to the framer, for inserting the frame that surrounds the face in the third image.
