A Dictionary Learning Based Kernel Sparse Representation Method for Face Recognition
Wan Yang · 2012
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.
