ABSTRACT:
The present invention is a method and apparatus for mapping digital image data using paired erosion-based filters. One filter of the pair creates a superset of the output image data and the other a subset of the output image data, and combinatorial logic is then applied to the superset and subset data to obtain the mapped image data. In one embodiment a plurality of erosion-based filters are used where one filter of the pair is extensive and the other filter is antiextensive, each pair generating a sample phase of a high resolution output image.
