Symmetry parameters for 3D pattern classification
The Winternitzs parameter enables to evaluate a symmetry degree for a given 2D convex body, with respect to a particular point. This point is the best-centered point according to symmetry criteria. The generalization of this parameter in 3D is studied and a second 3D-parameter is derived from the 2D-Winternitzs parameter.
