| 摘 要： | 受Metafaces方法的启发，提出一种基于字典学习方法的核稀疏表示方法并成功应用于人脸识别。首先，采用核技术将稀疏表示方法推广到高维空间得到核稀疏表示方法。其次，借鉴Metaface字典学习方法，进行字典学习得到一组核基向量构成核稀疏表示字典。最后，利用学习得到的核字典基重构样本，并根据样本与重构样本之间的残差最小原则对人脸图像进行分类。在AR、ORL和Yale人脸数据库上的实验表明该方法的良好识别性能。 |

| Abstract: | Inspired by Metafaces, a dictionary learning based kernel sparse representation method for face recognition is presented. Firstly, a kernel sparse representation classifier is proposed by extending sparse representation classifier to high dimensional space via kernel functions. Then, the kernel dictionary bases are learned based on Metafaces framework. Finally, the samples are reconstructed by kernel dictionary and the face images are classified according to the residual. The experimental results on AR, ORL and Yale face databases show that the proposed method works well. |
