Abstract
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.
