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 imagerecognition 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.
