| Abstract: | This paper focuses on the classification recognition of signature image by using wavelet transform and RBF neural network which contains different signature-image classification and similar signature-image classification.The proposed methods include feature extraction of image in wavelet domain and mode classification through RBF neural network.The analysis in time domain and frequency domain is especially effective when adopting multi-resolution analysis of signature image.The concept of entropy and energy concerned feature is applied to the wavelet domain.The RBF neural network owns fast speed in convergency and classification.The result of simulations proves the effectiveness of this method with the successful recognition rate of 100%. |
