Shape Features of 2D Figures
Zoltán Szakál, Ibolya Zsoldos · Materials science forum · 2010
The symmetry-diagram was originally defined for symmetry recognition. As a consequence it has been proven that the symmetry-diagram shows the unique shape property of the two-dimensional (2D) figures. The symmetry-diagram is different in the case of 2D figures having a different shape. It is very sensitive to the smallest change in the shape. The only exception for its applicability is the 2D figure having two or more concentric boundary loops.
