<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.
