Abstract

Purpose: In face reocognition area, estimating occlusion in face images is on the rise. In this paper, we propose a new face recognition algorithm based on dual sparse representation to solve this problem.
Method: Each face image is partitioned into several pieces and sparse representation is implemented in each part. Then, some parts that have large sparse concentration index are combined and sparse representation is performed one more time. Each test sample is classified by using the final sparse coefficient where correlation between the test sample and training sample is applied.
Results: The recognition rate of the proposed algorithm is higher than that of the basic sparse representation classification.
Conclusion: The proposed method can be applied in real life which needs to identify someone exactly whether the person disguises his face or not.
