Russetal. (2006)presentsa3DapproachforrecognizingfacesbasedonPrincipalComponentAnalysis (PCA). This work was applied with face recognition. It avoids elimination of size information by scaling a 3D reference to enable alignment of facial points important for PCA training, synthesis, and recognition. This approach shows the improvement in the recognition accuracy and dimensional reduction.
