Glossary for Geospatial Science

color separation:� Manipulating a full-color image in order to extract features of one color or range of colors.� The color separation process can be used to create a binary raster object from a composite color raster object (or a set of three RGB raster objects) to lift out blue line images, for example, leaving behind background colors and lines images of other colors.� Printers use related color separation techniques to prepare process color separates from full-color originals.
