A new boundary shape description based on the notion of curvature-scale is presented. This shape descriptor performs better than the commonly used Rosenfeld's method of curvature estimation and can be applied directly to digital boundaries without requiring prior approximations. It 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 produces a complete boundary shape description capable of handling different levels of shape detail. It also has numerous potential applications such as automatic landmark tagging which becomes necessary to build model-based approaches toward the goal of organ modelling and segmentation.
