ABSTRACT:
An image having at least one high frequency feature is encoded by (a) filtering the image to produce a filtered image representing the image minus the at least one high frequency feature; (b) resolving the filtered image into at least one lower level of resolution; (c) encoding a correction image at the at least one lower level of resolution; (d) producing an expanded result image having the same the level of resolution of the image; and (e) encoding at the level of resolution the image the difference between the image and the expanded result image.
