                         skeletonization of binary shapes through numerical calculation of 
                         vector fields and curvature estimation by using the Weingarten 
                         formulae. It can be shown that potential valleys generated by 
                         vector fields have a close relationship with the definition of 
                         Intensity Axis of Symmetry. Given a binary image, the algorithm 
                         consists in generating a grayscale image corresponding to the 
                         magnitude of a vector field followed by a search of the points 
                         that belong to the bottom of the potential valleys or regions with 
                         minimum magnitude. It can be shown that these points provide a 
                         good approximation to the Medial Axis of the object in study. 
                         Also, the proposed method demonstrated good performance due to the 
                         fact that the vector field can be easily and rapidly calculated 
                         using the Fast Fourier Transform algorithm.",
