Supervised within-class-similar discriminative dictionary learning for face recognition.
Journal of Visual Communication and Image Representation(2016)
摘要
•A discriminative dictionary learning algorithm is put forward for face recognition.•The algorithm combines the linear classification error with the within-class scatter.•The fisher ratios of the coefficients are enhanced.•The proposed method outperforms some state-of-the-art dictionary learning algorithms.
