Master thesis (pre-Bologna period)
Covenantee: École polytechnique fédérale de LausanneEnglish: in this thesis, we address the problem of learning a face manifold model from an input data, consisting of 2D face images such that the input images can be approximated well using the learned manifold. We compute ...
