Abstract

See full text

Hand recognition system that compares narrow band ultraviolet-absorbing skin chromophores to identify a subject. Ultraviolet images of hands show much greater detail than visible light images, so matching of ultraviolet images may be much more accurate. A database of known persons may contain reference ultraviolet hand images tagged with each person's identity. Reference images and subject images may be processed to locate the hands, identify features (such as chromophores), compare and match feature descriptors, and calculate correlation scores between the subject image and each reference image. Locating and normalizing hand images may use infrared and visible light cameras in addition to ultraviolet. If the subject is moving, the subject's hand may be tracked, a 3D model of the subject's hand may be developed from multiple images, and this model may be rotated so that the orientation matches that of the reference images.
