Restricted nearest feature line with ellipse for face recognition

In this paper, a novel classifier based on nearest feature line is proposed, which is called as restricted nearest feature line with ellipse (RNFLE). NFL successfully improves the classification ability. However there are still some drawbacks in NFL that limit their further application in practice. To improve the miss-classification of nearest feature line when the prototypes in NFL are far away from the query sample, RNFLE uses the ellipse to restrict the feature lines. A large number of experiments executed on ORL and AR face database confirm the usefulness of the proposed algorithm. © 2012 ISSN 2073-4212.
