In particular, in a class of pictures called line images, the major feature is a line or vector. Raster representations of line images, while common, are quite wasteful of storage and are difficult to manipulate. If the vectors could be extracted reliably from the raster image, then rotation, scaling, plotting, and many other operations could be speeded up enormously.EngComputer Scienceunknown1987-259-0710.11575/PRISM/30939
