A similarity measure of deformable shapes

A set of 0-, 1- and 2-dimensional primitives is used to represent plane shapes. For each of these primitives a kind of energy is assigned. This energy model includes binding effects which can explicitly handle perceptual organization. A set of deformations of perceptual meaning is used to evaluate shape perceptual similarity. This similarity measure includes only limited deformation modes of perceptual meaning; it includes both structure salience and metric difference; it incorporates both region and contour influence; and it tackles perceptual organization explicitly. Some examples show that this similarity model partially captures human perceptual similarity judgment of simple plank shapes
