On the construction of gestalt-algebra instances and a measure for their similarity
Four construction principles that compose more complicated percep-tual gestalts from less complex ones are defined in detail: Mirror gestalts, lattice gestalts, rotational mandalas, and clusters, respectively. These can be encapsu-lated as constructions in a production system. Since any of the four construc-tions can work on any gestalt, a recursive and very expressive scheme is set up with many prospective applications in image mining. Of particular interest is such analysis for aerial and satellite images and for façade images of buildings.
