Firstly, the digital character is processed by mathematics morphology for its special typeface structure. Then, the character is analyzed by wavelet packet for three layers to get the coefficients in nodes of the third layer. In addition, the nodes of the second layer are reconstructed and the Zemike moments of the reconstructed images are computed individually. At last, the coefficients of the third wavelet packet and the Zemike moments make up the feature space, which is processed by reducing the dimension. The digits of the vehicle license plate are recognized by BP neural network. The experimental results demonstrate the efficiency of the proposed approach. %U http://cea.ceaj.org/EN/abstract/article_16717.shtml
