CONTRAST MODULATION TECHNIQUES FOR IMAGE ENHANCEMENT.
Abstract
A program was undertaken to find a better way to interpret information recorded on a silver-halide photographic emulsion. The information of major interest was that which was below the threshold of human vision, being obscured because of low density differences caused by improper exposure or other effects. The proposed program of research and development consisted of three basic parts: a study of enhancement techniques in general, a design study of the instrumentation techniques required to achieve the most promising enhancement principles, and the fabrication of the necessary laboratory apparatus to demonstrate these techniques.
