局部结构保持的鉴别分析方法
DISCRIMINANT AND ANALYSE METHOD OF LOCAL STRUCTURE PRESERVING
摘要
Abstract
Locality Preserving Projections (LPP) is an algorithm of local feature extraction, it can preserve local geometrical structure of the data set effectively. On the basis of LPP, Uncorrelated Discriminant Locality Preserving Projections ( UDLPP) utilises label information, and achieves good discrimination capability by preserving the within-class geometric structure, while maximizing the between-class distance. A discriminant and analyse method of local structure preserving, called PCLSP, is proposed based on UDLPP and with the idea of UDLPP, which not only uses the label information of the data set but also takes the local information of the data set into account. It enhances discrimination capability by minimizing the scatter of within-class neighbourhood and maximizing the scatter of between-class neighbourhood, therefore further reflects the local structure information of the data set and increases the recognition rate. Experimental results on ORL and YALE face databases indicate that the proposed algorithm is effective.关键词
