An SE(3) invariant description for 3D face recognition

摘要

Here, we intend to introduce a novel 3D face description which is invariant under the Special Euclidean group SE(3) and independent to the original surface parameterization. It is well known that it is too difficult to define a relative invariant parameterization of a general curved surface. In the present work, we introduce the multi-polar geodesic representation of ℝ3 surfaces. It allows to reach an isotropic canonical parameterization relatively to SE(3) due to the fact that the face surfaces can be easily assumed to be a graph of a function from ℝ2 to ℝ. The principal curvature fields according to a three-polar parameterization are considered. A statistical study is made to choose a good configuration of reference points. The performances of the novel description are tested on the standard database FRGC v2.0. Many recognition scenarios are established. The obtained results are very competitive with the state of the art.
