Face recognition algorithm based on cascade sparse representation-based classifier

For problem of high complexity, slow identification of algorithm based on sparse representation-based classifier, the paper proposed face recognition algorithm based on cascade sparse representation-based classifier. The algorithm uses ideas of cascade, through repeated using of sparse representation-based classifier to determine the class which the sample to be classified belongs to step by step and accurately. The algorithm reduces computational complexity and identifying difficulty, and reaches goals of high recognition rate, good robustness and fast identifying speed.
