Subpattern Locality Preserving Projections for face recognition
Chongwen Liu · 2011
To improve the robustness of the Locality Preserving Projections(LPP)to variation in illumination,expression and so on,a novel approach called Subpattern Locality Preserving Projections(SPLPP) was proposed for face recognition.In the SPLPP framework,samples were first divided into many non-overlapping subpattern sets and then LPP method was used on each of set,nearest neighbor classifier was used for classification in the end.The experimental results on Yale,ORL,FERER face databases illustrate that the proposed SPLPP method is superior to PCA,LDA and LPP in terms of recognition rate.
