In real-world face recognition systems, traditional face recognition algorithms often fail in the case of insufficient training samples. Recently, the face recognition algorithms of sparse representation have achieved promising results even in the presence of corruption or occlusion. However a large over-complete and elaborately designed discriminant training set is still required to form sparse representation, which seems impractical in the single training image per person problems. In this paper, we extend Sparse Representation Classification (SRC) to the one sample per person problem. We address this problem under variant lighting conditions by introducing relighting methods to generate virtual faces. Our diverse and complete training set can be well composed, which makes SRC more general. Moreover, we verify the recognition under different lighting environments by a cross-database comparison.
