Under the present invention, an image is progressively blurred to yield a
set of (progressive) scaling levels. Once blurred, the edges of the image
are detected so that each image segment can be identified on each scaling
level. Once the segments are identified, like segments (i.e., segments
having a like edge/Gaussian operator) on successive scaling levels are
linked to yield a lattice structure that represents the perceptual
organization of the image.
