Classifying master images method for electronic reproduction, according to positive and negative images, involves classifying the master images and illustrations on the basis of their color mask probability

摘要

The method of classifying master images (slides/transparencies, color negatives etc) and illustrations etc. The classification is based on the picture elements of the master images being entered as picture element (pixel) data in a color system with several color components, and developing a mask membership function (mu r) for the picture elements from the color-spacing (-difference) from the color mask values (Ak,Bk).
