摘要:

Supervised locally linear embedding method and linear discriminant analysis method are proposed in this paper for face recognition. As face images are regarded as a nonlinear manifold in high-dimensional space, supervised locally linear embedding method is utilized to nonlinearly map high-dimensional face images to low-dimensional feature space. To recover space structure of face images, morphable model is utilized to derive multiple images of a person from a single image. Experimental results on ORL and UMIST face database show that our method makes impressive performance improvement compared with conventional Fisherface methods.
