- Abstract:
-
Traditional small-sample face recognition methods based on dictionary learning have disadvantages such as poor dictionary discrimination and lack of robustness. In this paper, we propose a sparse comprehensive dictionary learning model. This model effectively utilizes and generates facial changes, expands the diversity of training samples by the mirror principle and Fisher’s criterion, and extracts the commonalities, specialties, and anomalies between different categories of data by constructing a hybrid feature dictionary, extended interference dictionary, and low-rank dictionary atoms. This strategy improves the recognition rate of the algorithm and its ability to handle abnormal situations such as expression changes, pose changes, and occlusions. The results of simulation experiments performed on the face databases AR, YALEB, and LFW verify the effectiveness and feasibility of the proposed algorithm.
