image processing
<graphics> 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.
