7 Binarization and Color Separation This chapter describes the procedures of converting color and grayscale images to monochrome raster images (raster layers). The original image is a raster file, obtained after color or grayscale scanning. Binarization creates monochrome raster images, containing black-and-white representation of color objects. For example, from one image of a scanned map you can extract and place to separate monochrome layers the objects of different color: isolines, roads, rivers, and other objects. This method provides the means to place objects that have one or several different colors on the original image, to the same monochrome layer. Another method to obtain a monochrome image from a color one is by color separation. WiseImage can convert a color image to a set of monochrome raster layers. A black-and-white representation of each pixel of the original image will be placed on a particular layer. You can further convert the obtained monochrome images to vectors using vectorization or tracing. Vectorization of a layered raster image is considerably more effective than vectorization of an original color scan.
