Morphological shape representation

A new approach for shape representation is described which provides a general scheme for object description and unifies some of the existing representation techniques (e.g. CSG, skeletons, shape decomposition). It is based on the use of simple geometric objects which are intuitively used by humans in their perception of shapes and on mathematical morphology. Furthermore, its unifying framework can be used both in computer graphics and computer vision, thus providing a tool to close the existing gap between object modeling and object recognition in certain applications, e.g. in robotic vision
