abstract = "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 polygonal meshes
from signed octrees. It determines the positioning of the vertices
of the mesh by minimizing a quadratic error expressed in terms of
hermitian data. In order to apply dual contouring on volumetric
reconstruction from silhouettes we devised a method that is able
to determine the discrete topology of the contour in relation to
the octree cells, as well as the hermitian data corresponding to
the intersections and normals of conic volumes whose intersection
approximates a structure known as Visual Hull. Due to the discrete
and extremely noisy nature of the data used in the reconstruction
we had to devise a different criterion for mesh simplification
that applies topological consistency tests only when the geometric
error measure is beyond a given tolerance. We present results of
the application of the proposed method in the extraction of a mesh
corresponding to the surface of objects of a real scene.",
