DT-CWT Feature Based Face Recognition Using Supervised Kernel ONPP
Yuehui Sun · Computational Intelligence and Security · 2007
A novel DT-CWT feature-kernel face recognition method is proposed in this paper. This involves transforming a face image with DT-CWT on feature extraction stage, and supervised kernel Orthogonal Neighborhood Preserving Projections (ONPP) being then automatically applied to the feature vectors. Numerical experiments are reported to illustrate the performance of our algorithm and to compare it with a few competing methods.
