Polygonization of volumetric reconstructions from silhouettes
In this work we propose a method for the polygonization of octree-based reconstructions by dual contouring. Dual contouring is an adaptive method for determining contiguous polygo...

DL Meet FL: A Bidirectional Mapping between Ontologies and Linguistic Knowledge
We present a transformation scheme that mediates between description logics (DL) or RDF-encoded ontologies and type hierarchies in feature logics (FL). The DL-to-FL direction is i...
