To solve the problem of efficiently identifying certain structural characteristics in large sets of data, an algorithm is developed which enables, in any Euclidean space, the determination of a subset of a point set A which is small, but nonetheless meaningful for certain structural characteristics. This so-called set of Characteristic Vertices of A is determined as the solution of a non-linear optimization problem from the set of extreme points of the convex hull of A.
In order to illustrate that this approach enables the complexity of a pattern recognition problem to be reduced, an algorithm is developed to determine approximate n-symmetries of point sets in Euclidean spaces of any dimension. By assigning symmetry values, this algorithm is particularly suitable to enable the identification of incomplete or projectively distorted symmetries.
