image processing

    Computer manipulation of images.  Some of the
   many algorithms used in image processing include
   convolution (on which many others are based), FFT, DCT,
   thinning (or skeletonisation), edge detection and
   contrast enhancement.  These are usually implemented in
   software but may also use special purpose hardware for
   speed.

   Image processing contrasts with computer graphics, which is
   usually more concerned with the generation of artificial
   images, and visualisation, which attempts to understand
   (real-world) data by displaying it as an artificial image
   (e.g. a graph).  Image processing is used in image
   recognition and computer vision.

   Silicon Graphics manufacture workstations which are often
   used for image processing.  There are a few programming
   languages designed for image processing, e.g. CELIP, VPL.
