Extending color vision methods to bands beyond the visible

Abstract

There is a rapid growth in sensor technology in regions of the electromagnetic spectrum beyond the visible. Also, the parallel growth of powerful, inexpensive computers and digital electronics has made many new imaging applications possible. Although there are many approaches to sensor fusion, this paper provides a discussion of relevant infrared phenomenology and attempts to apply known methods of human color vision to achieve image fusion. Two specific topics of importance are color contrast enhancement and color constancy.
