                         its points using non-linear curvature filters. We give a 
                         mathematical proof that an image can be reconstructed from the 
                         regions of non-zero gaussian curvatures. This result provides the 
                         theoretical background for a new theory of non-linear two 
                         dimensional signal processing as proposed by C. Zetzche, E. Barth 
                         and B. Wegman ([15, 16]). We use curvature measures to detect 
                         edges and vertices (roughly two dimensional regions) and show that 
                         reconstruction is possible from these elements.",
