graphics Computer manipulation of images. Some of the
many algorithms used in image processing include
convolution (on which many others are based), FFT, DCT,
contrast enhancement. These are usually implemented in
software but may also use special purpose hardware for
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.
