Abstract

Variational techniques are a popular approach for reconstructing the surface of an object. In previous work, the surface is represented either implicitly by the use of level sets or explicitly as a triangle mesh. In this work, we choose a point-based surface representation. The rational behind is that the lack of topology information in point-based models makes it easier to handle topological changes occurring during the reconstruction. \par We first describe our approach for synthetic objects whose geometry is precisely known. We then transfer this method to real world data and describe the modified algorithm in detail.
