1. A method for automatically processing digital image data consisting of image information, the method comprising the steps performed by a data processor of:

  • storing the image data in the data processor;

    generating a plurality of uniquely addressable domain blocks from the stored image data, each of the domain blocks representing a different portion of the image information such that all of the image information is contained in at least one of the domain blocks;

    creating, from the stored image data, a plurality of uniquely addressable mapped range blocks corresponding to different subsets of the stored image data with each of the subsets having a unique address, the creating step including the substep ofexecuting, for each of the mapped rangeblocks, a corresponding procedure upon the oneof the subsets of the stored image data whichcorresponds to the mapped range block;

    assigning unique identifiers to corresponding ones of the mapped range blocks, each of the identifiers specifying for the corresponding mapped range block a procedure and a address of the corresponding subset of the stored image data;

    selecting, for each of the domain blocks, the one of the mapped range blocks which most closely corresponds according to predetermined criteria; and

    representing the image information as a set of the identifiers of the selected mapped range blocks.
