Abstract
A method for representing a digital image in a plurality of image processing states using at least one reference digital image and at least one residual image comprising the steps of manipulating an input digital image using at least one digital image processing enhancement step to form at least one additional digital image in a different image processing state; designating at least one of the digital images to be a reference digital image in a reference image processing state; and determining at least one residual image representing differences between one of the reference digital images and one of the additional digital images, whereby the residual image(s) and the reference digital image(s) can be used to form digital image(s) in different image processing states.
