PSEUDOCOLOR IMAGE ENHANCEMENT BY A TWO-SEPARATION PHOTOGRAPHIC PROCESS,
Abstract
A continuous-tone black-and-white image contains intensity information equivalent to an infinite number of shades of grey. In viewing such a complex scene, the human eye can distinguish only about 15 or 20 grey levels. Since the eye can distinguish many more colors under such circumstances, a transformation of the grey scale into a chromatic scale, in which each intensity level of the original is presented as a different color, offers the possibility of transmitting more of the image information to an observer. The authors discuss the usefulness of such transformations of imagery in the fields of medicine, aerial reconnaissance, criminology, etc. (Author)
