文摘
- •
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.
