Detailed Description

A class for isotropic normalizations of point sets.

The points are translated so that their center of gravity lies in the coordinate's system origin. Both axis are scaled to ensure an average distance of the points to the origin, e.g. 1 or sqrt(2). The same scale factor is applied to both axis.
