Implementation of 3D Face Construction from a Face Image

Shape reconstruction of an object from a two-dimensional image is an ill-posed problem in its nature where additional information is needed. Lately, researchers suggested an approach that a reference shape of similar objects is to be used during the reconstruction. This method introduces a promising alternative to regular shape from shading algorithms. Moreover, in face reconstruction problems, spherical harmonic expansion of the reflectance simplifies the solution further. In this paper, an iterative reconstruction algorithm is tested in order to determine optimal values of some parameters. Test results confirms that the algorithm is somewhat sensitive to searched parameters.
