Computing dominant points on simple shapes

Gestalt psychologists have given many examples to demonstrate that laws of visual organization cause one view of a scene to dominate others. This is also true for simple shapes. A figure can be articulated into many fragments but only a few will be perceptually dominant. The analysis of shape requires that the computations underlying the articulation be made explicit. Possible computations have been investigated on convex blobs, the dominant units being corner-like regions. Each region is considered to have a point which perceptually dominates other points in that region. The problem, then, is how to attribute a set of points to some point so that the set is perceived as a meaningful fragment of the blob.
