An application of nonlinear wavelet approximation to face recognition
L.H. Yang, Thi Thu Trang Bui, C.Y. Suen · 2003
In this paper we present an application of the nonlinear wavelet approximation to recognize faces. The advantages of the nonlinear wavelet approximation are compared with its linear counterpart. An efficient scheme in applying the nonlinear wavelet transform to face recognition is presented. Experiments using the Yale Face Library show very encouraging recognition results and demonstrate that this method has the desirable property of being insensitive to facial expressions.
