title: Topological Noise Removal

Meshes obtained from laser scanner data often contain topological noise
due to inaccuracies in the scanning and merging process. This
topological noise complicates subsequent operations such as
remeshing, parameterization and smoothing. We introduce an approach that
removes unnecessary nontrivial topology from meshes.  Using a local wave
front traversal, we discover the local topologies of the mesh and identify
features such as small tunnels.  We then identify non-separating cuts
along which we cut and seal the mesh, reducing the genus and thus the
topological complexity of the mesh.
