White-light image addition and subtraction by calorimetric measurement.
The theory and experiment of a new white-light image-processing technique for black-and-white image addition and subtraction by means of Fourier-plane spatial color filtering are described. Both the intensity transmittances of three (or two) processed images and the results of the addition and subtraction are expressed in a chromaticity coordinate system.
