Group Averaged Linear Transforms that Detect Corners and Edges
December 1975 (vol. 24 no. 12)
pp. 1191-1201
J.C. Dunn, Department of Theoretical and Applied Mechanics and the Center for Applied Mathematics, Cornell University
Linear transforms of the characteristic functions of plane figures are averaged over the one parameter continuous group of dilatations (homothetic scale changes) to obtain new dilatation-invariant transforms. For a large class of kernel functions, the group averaged transforms act as corner detectors or edge detectors.
Index Terms:
Artificial neurons, corner detection, edge detection, group averaging, linear transforms, pattern classification, plane figures, scale-invariant features, transformation invariants, threshold logic networks.
