ABSTRACT
Digital image 6 processing Digital image processing is the general term used to describe a wide range of operations carried out to digital images. Strictly speaking, any digital image that is modified in any way by a computer has been processed, and the applications are widespread. Much of the current technology has resulted from the work of NASA, who have been enhancing and analysing images transmitted back from spacecraft for over 30 years. The most famous example is perhaps that of the Hubble space telescope, whose distorted images were partially corrected by digital image processing before it could be physically repaired in space. Other major applications include medical imaging and machine vision (where cameras monitor production lines, and can be programmed to automatically reject faulty components).
