Abstract:
1. A method for recovering an image defined as a function of image coordinates of an image space from compressed data that is a function of transform coordinates in a transform space comprising: a) transforming said compressed data using at least one partial transform that transforms at least one but not all of the transform coordinates into a corresponding image coordinate to generate a set of intermediate coefficients which are functions of at least one coordinate from the image space and at least one coordinate from the transform space in a space intermediate between said transform space and said image space said intermediate space being defined by at least one coordinate from the image space and at least one coordinate from the transform space; b) adjusting the value of at least one intermediate coefficient and using said adjusted value to generate a set of adjusted intermediate coefficients; and c) recovering said image by transforming said set of adjusted intermediate coefficients to said image space with at least one additional partial transform.
