image processing : FOLDOC | 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. See also Pilot European Image Processing Archive. Usenet newsgroup: {news:sci.image.pro
