The recognition of faces under varying expressions is one of the current challenges in the face recognition community. In this paper, we propose a method fusing different complementary approaches each dealing with expression variations. The first approach uses an isometric deformation model and is based on the largest singular values of the geodesic distance matrix as an expression-invariant shape...
Currently, the recognition of faces under varying expressions is one of the main challenges in the face recognition community. In this paper a method is presented dealing with those expression variations by using an isometric deformation model. The method is built upon the geodesic distance matrix as a representation of the 3D face. We will show that the set of largest singular values is an excellent...
