| Abstract: | Paper currency sorting is an important operation in the bank, and the technique for Chinese paper currency sortor is still a lacuna in China A real time paper currency recognition method is proposed in this paper, which extracts the directional block characteristics and the size information of a currency image as the recognition features A modified Kohonen network is constructed for the recognition of Chinese paper currency The experiment reveals that this method achieves a high recognition rate and fast recognition speed The proposed method has been applied to a practical sorting system |
