The method makes reduced resolution versions of the original image available for quick display on video monitors while providing access to the full resolution image for photographic quality hardcopies. This multiresolution method also provides for the efficient storage of this data via a hybrid coding scheme based on residuals. Several embodiments of this approach are described. | |
