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}.
