Abstract

The Generalized Hough Transform is an established technique for geometric shape matching. An analogous technique is presented here for approximate solution of subgraph isomorphism problems. Its chief advantages are that it can also be used to find partial isomorphisms and that it can be readily implemented in parallel on a network of simple processors.
