Abstract(in English) | In this paper, we propose a method for estimation of a surface from cloud of noisy samples. We formulate the variational method for the collection of sample points. And we derive a numerical method for the computation of approximated solution. The criterion for our variational problem basically depends on distance measure and angles between portions of a polyhedral surface. The distance measure controls the convergence of criterion locally, while the angle measure controls the convergence of the criterion globally. The criterion is also valid for the k-dimensional manifold in n-dimensional Euclidean space for k < n. Since our method automatically learns the topology of the collection sample points, first assuming it topology as an open surface, second evaluating a condition, and third detecting the correct topology of a sample cloud which expresses the geometrical concept. |
