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.
