Genus refinement of a manifold surface reconstructed by sculpting the 3d-Delaunay triangulation of Structure-from-Motion points

The automatic surface reconstruction from an image sequence is still an active research topic. Recently, a method was designed to reconstruct a 2-manifold surface from the sparse cloud of points generated by Structure-from-Motion (SfM). This method reconstructs outdoor scenes from hundreds of catadioptric images. It is based on sculpting the 3d Delaunay triangulation of the points by ray-tracing. Our paper improves the resulting surface by removing spurious handles, which occur frequently.
