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.
