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.
