ABSTRACT:
An image processing method is described for the hierarchical storage and display of high resolution digital images in a multiuse environment. 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 making photographic quality hardcopies. This multiresolution method also provides for the efficient storage of the data resulting from the use of this method via a hybrid coding scheme. Several embodiments of the method are described.
