摘要：Subspace-based face recognition is one of the most successful methods for face recognition. Eigenfaces, Fisherfaces, and Laplacianfaces methods, which are based on PCA, LPP and LDA that preserve global, local and cluster structure information respectively, are three representative methods of subspace-based face recognition approaches. In this paper, we propose a novel pattern classification namely Preserving Complete Subspace Structure Projection (PCSSP) for face recognition. First we analyze their contributions of extracting the discriminating information respectively firstly, and then we construct a 3D parameter space using three subspace dimensions as axes. We can take advantage of the global, local and cluster structure information provided by three subspaces through searching over the whole 3D parameter space instead of searching only in lines or local regions as the standard subspace methods. Finally based on the 3D parameter space, we propose a framework for PCA, LPP and LDA. The experimental results with the ORL and Yale face databases show that the proposed algorithm outperforms three standard subspace approaches, and the proposed algorithm can also improve the computational efficiency without influencing the recognition performance.
