PSEUDOCOLOR ENHANCEMENT OF BIOMEDICAL IMAGES,

Abstract

For human observers, the number of distinguishably different colors is much larger than the number of distinguishably different shades of gray. Therefore, if the scale of grays in a complex black-and-white image is transformed into some suitable scale of colors, perception of the details in that image will be greatly enhanced. In one versatile but expensive method of producing such pseudocolor images, the black-and-white image is photoelectrically scanned and a computer used to produce three pseudocolor separations on 35-mm film. A simpler and inexpensive method uses purely photographic procedures. Examples of pseudocolor enhancements are presented. (Author)
