| Abstract: | This paper proposes a novel locality preserving projections (LPP) algorithm for image recognition, namely, the direct locality
preserving projections (DLPP), which directly optimizes locality preserving criterion on high-dimensional raw images data
via simultaneous diagonalization, without any dimensionality reduction preprocessing. Our algorithm is a direct and complete
implementation of LPP. Experimental results on the PolyU palmprint database and ORL face database show the effectiveness of
the proposed algorithm. |
