Claim One:
1. A computer-implemented method for representing a perceptual organization of an image, comprising using at least one computer to perform the steps of: progressively blurring the image to yield a set of scaling levels, and allocating a spatial index that comprises a rectangular array of integers for each of the set of scaling levels; detecting edges of the image on each of the set of scaling levels; identifying individual segments of the image on each of the set of scaling levels based on the detected edges, and assigning each of the individual segments a non-zero integer as an identifier, wherein corresponding elements of the associated spatial index are set to the identifier; and linking like individual segments on successive scaling levels based on a comparison of corresponding identifiers of the individual segments to yield a lattice structure, wherein the lattice structure represents the perceptual organization of the image.
