Image Processing

Image processing is a branch of signal processing for which the input is an image, a set of images, or a video. The output of an image processing function or system is usually of the same form as the input, but may include certain parameters about the input image(s) that have been determined.

Optical and analog image processing exist in non-computer systems, but in this wiki we focus on digital image processing. Image processing is a broad topic. Further exploration can be found by looking at related fields and subfields such as image sharpening, image smoothing, and computer vision.
