Noise is a serious problem that hinders high quality digital image processing. In digital photography, the consumer- and prosumer-level cameras produce images with an easily noticeable noise component which is especially strong in images taken at high ISO rates. Scanned photos contain a similar film grain component. The noise and grain reduce the visual quality of digital images and resulting printouts.
