Abstract

Face recognition is a popular application of pat- tern recognition methods, and it faces challenging problems including illumination, expression, and pose. The most popular way is to learn the subspaces of the face images so that it could be project to another discriminant space where images of different persons can be separated. In this paper, a nearest line projection algorithm is developed to represent the face images for face recognition. Instead of projecting an image to its nearest image, we try to project it to its nearest line spanned by two different face images. The subspaces are learned so that each face image to its nearest line is minimized. We evaluated the proposed algorithm on some benchmark face image database, and also compared it to some other image projection algorithms. The experiment results showed that the proposed algorithm outperforms other ones.

Face Recognition via Globality-Locality Preserving Projections
Gloablity-Locality Preserving Projections (GLPP) can preserve both the global and local geometric structures of data. The proposed face recognition methods outperform the current state-of-the-arts.

Discriminant analysis based on projection onto generalized difference subspace
This paper discusses a new type of discriminant analysis based on the orthogonal projection of data onto a generalized difference subspace (GDS) We prove that gFDA is equivalent to GDS projection with a small correction term.

Collaborative Discriminant Locality Preserving Projections With its Application to Face Recognition
We present a novel Discriminant Locality Preserving Projections (DLPP) algorithm. We apply our algorithm to face recognition. Three popular face databases are employed for evaluating the performance of CDLPP.

Relaxed 2-D Principal Component Analysis by Norm for Face Recognition
A relaxed two dimensional principal component analysis (R2DPCA) approach is proposed for face recognition. Numerical experiments on practical face recognition indicate that the R2D PCA has high generalization ability and can achieve a higher recognition rate.

Discriminant Projection Representation-based Classification for Vision Recognition
A novel method called projection representation-based classification (PRC) is proposed for image recognition. PRC is based on a new mathematical model. It is able to approximate the 'ideal representation' of each subject.

Random Subspace Two-dimensional LDA for Face Recognition
A novel technique named random subspace two-dimensional LDA(RS-2DLDA) is developed for face recognition. This approach offers a number of improvements over the random sub space two- dimensional PCA (RS2DPCA) framework.
