Skeleton Representation based on Compound Bezier Curves

A new method to describe the skeleton of a polygonal figure is presented. The skeleton is represented as a planar graph, whose edges are linear and quadratic Bezier curves. The description of a radial function in Bezier splines form is given. An algorithm to calculate control polygons of Bezier curves is proposed. Also, we introduce a new representation of skeleton as a straight planar control graph of a compound Bezier curve. We show that such skeleton representation allows simple visualization and easy-to-use skeleton processing techniques for image processing.
