A novel scheme for 3D face recognition based on partial differential equations

In this paper, we proposed a novel scheme to recognize 3D face based on partial differential equations (PDE). We proposed a novel distance between two boundary curves using the difference of the corresponding Fourier series coefficients. The distance of each adjacent boundary curves is taken as the feature of 3D face for recognition. Moreover, resemblance distance algorithm is applied for recognition. Experiment results and analysis show that the proposed scheme has a high identification rate in neutral 3D face database.
