Abstract
This presentation describes an experimental method of image contrast en-hancement adaptable to a variety of photo interpretative disciplines including radiology. Because of the relatively low order of spatial frequency resolution required for interpretation of radiographs, it is in this area that the principle can first be brought to a state of practical application. In the course of the work reported here, a laboratory bread-board, satisfactorily demonstrating the usefulness and practicability of the contrast enhancement technique, was fabricated and evaluated.
