  abstract = "We consider the problem of approximating the 3D
              scan of a real object through an affine combination of
              examples. Common approaches depend either on the
              explicit estimation of point-to-point correspondences
              or on 2-dimensional projections of the target mesh;
              both present drawbacks. We follow an approach similar
              to [IF03] by representing the target via an implicit
              function, whose values at the vertices of the approximation
              are used to define a robust cost function. The
              problem is approached in two steps, by approximating
              first a coarse implicit representation of the whole
              target, and then finer, local ones; the local approximations
              are then merged together with a Poisson-based
              method. We report the results of applying our method
              on a subset of 3D scans from the Face Recognition
              Grand Challenge v.1.0."
