Abstract

Structural analysis and description depend on the topological structure of the shape, and therefore, they are sensitive to discontinuous transformations which change the topology of the shape. In this paper, we give a complete analysis of the a priori effects of some commonly occurring discontinuous transformations. Some systematic transformation laws have been obtained based on the shape description in terms of quasi-convexity/concavity and quantized directional features. We mention some applications of the analysis.
