Human recognition has become an essential part of variety of applications ranging from security, surveillance, control, etc. It has become an important aspect when it comes to issues like authentication and identification. Human face can play an important role in identification. By developing better dimensionality reduction and feature extraction techniques, a large number of face recognition systems have come into existence. In this paper, the authors discuss and elaborate a recently proposed method based on Locality Preserving Projection (LPP) and Laplacian faces.
