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