A face detection and recognition system having several arrays imaging a
scene at different bands of the infrared spectrum. The system may use
weighted subtracting and thresholding to distinguish human skin in a
sensed image. A feature selector may locate a face in the image. The face
may be framed or the image cropped with a frame or border to incorporate
essentially only the face. The border may be superimposed on an image
direct from an imaging array. A sub-image containing the face may be
extracted from within the border and compared with a database of face
information to attain recognition of the face. A level of recognition of
the face may be established. Infrared lighting may be used as needed to
illuminate the scene.
