< 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 .
