Orthogonal Neighborhood Preserving Discriminant Projections for Face Recognition

Abstract

Feature extraction is an important step for face recognition. The capability of feature extraction directly influences the performance of face recognition. Recently, some manifold learning algorithms have drawn much attention. Among them, neighborhood preserving projections is one of the most promising feature extraction techniques. Though NPP has been… (More)
