Abstract
-
The use of pseudocolor transformations for the enhancement of black-and-white photographic images has a wide range of potential applications, including both tactical and strategic reconnaissance. The Report describes a simple and relatively inexpensive method of producing pseudocolor transformations by a photographic procedure in which three intermediate separations are obtained from a black-and-white original and then successively printed on color material. The density range and contrast of the separations are controlled by selectively varying the materials used, the exposure, and the processing technique. The final appearance of the pseudocolor transformation is then determined by an appropriate selection of filters and exposures during the successive printing, in register, of the three separations on color material. The principal result of the present work is that the proposed three-separation technique has been shown to produce a range of pseudo-color transformations which have potential for the enhancement of a variety of military and biomedical images.
