Large margin linear projection and face recognition

Unlike linear discriminant analysis, the large margin linear projection (LMLP) classifier presented in this paper, which also roots in linear Fisher discriminant, takes full advantage of the singularity of within-class scatter matrix, and classifies projected points in one-dimensional space by itself. Theoretical analysis and experimental results both reveal that LMLP is well suited for high-dimensional small-sample pattern recognition problems such as face recognition.
