Geometric Data Analysis: An Interactive Graphics Program for Shape Comparison.

Abstract

Two shapes, each consisting of n homologous points, can be rotated, scaled, and translated to obtain a close fit to each other by several methods. An interactive graphical computer program is presented that implements two methods: least squares and repeated medians, a robust method. Examples are given and the use of the system is discussed.
