                         landmarks on boundaries. Our method of boundary shape description 
                         is based on the notion of c-scale, which is a new local scale 
                         concept, defined at each boundary element. From this 
                         representation we can extract special points of interest such as 
                         convex and concave corners, straight lines, circular segments, and 
                         inflection points. The results show that this method gives a 
                         complete description of shape and allows the automatic positioning 
                         of mathematical landmarks, which agree with our intuitive ideas of 
                         where landmarks may be defined. This method is applicable to 
                         spaces of any dimensionality, although we have focused in this 
                         paper on 2D shapes.",
