Face Recognition Using Neural Network Based on Continuous Wavelet Transform
Institution:(Department of Automatic Control Engineering, Southeast University, Nanjing 210096)
Abstract:A face recognition method using neural network is proposed based on continuous wavelet transform. The theory of wavelet analysis is introduced. The method of selecting mother wavelet function is detailed according wavelet transform norm, and the number of wavelet knot and the initialization are decided by wavelet ridge. The training method of parameters is also introduced. Through continuous wavelet analysis and self-organizing and self-training of neural networks, the connection weights and the parameters of scales and positions are adapted to complete the task of face recognition. The test results shows that this method obtains much better performance in face recognition compared with the classical eigenface method.
Keywords:Continuous wavelet transform  Face recognition  Module maxima  Wavelet ridge
