Abstract:  A two-phase face recognition algorithm based on discriminative low-rank representation is proposed to deal with the noise in image training samples. In the first stage, all the training samples are processed by low-rank representation, and the M nearest neighbors of test sample are selected for rough classification. In the second stage, the samples screened in the first stage are used for discriminative low-rank representation, and sparse linear representation is used for fine classification, so as to determine the most suitable class labels for test samples. This algorithm combines the advantages of low-rank algorithm and sparse algorithm. The performance of this algorithm is proved by experiments on standard face database.
