A novel face recognition method called null space discriminant projection embedding(NDPE) is proposed.Based on locality preserving projections(LPP) and nonparametric discriminant analysis methods,NDPE can encode both the geometrical and discriminant structure of the face data manifold,and address the small sample size problem by solving an eigenvalue problem in null space.Dual tree complex wavelet transformation(DTCWT) is integrated with NDPE to improve the recognition performance.Experiment results on ORL,...
