In this paper, we propose a new dictionary learning method to improve the performance of face recognition by learning a shared dictionary for all persons and a class-specific dictionary for each person. Such shared-dictionary is employed by computing the differences between samples and the centroid of neutral-samples, which improves the representation effort in the case of pose, expression and occlusion changes. Moreover, the discriminative power of learnt class-specific dictionary is further… CONTINUE READING
