| Notes | For the problem of face recognition, such as disguise, occlusion, illumination and expression changes, a face recognition based on local feature and kernel low rank representation is proposed. First, it extracts the LBP feature of training and testing sam-ple image. Then it is projected onto the high dimensional feature space by the mapping function. The feature matrix which is pro-jected into the high dimension space is used to extract the common features of the samples by the method of low rank representa-tion after dimension reduction. Finally, it carries on the classified recognition based on the method of residual approximation. The ex-perimental results show that the proposed algorithm is robust to occlusion, camouflage and illumination changes. At the same time,compared with some of current face recognition algorithms, the recognition rate of this proposed algorithm has been significantly im-proved.
