| Abstract: | Independent Components Analysis (ICA)is an effective approach of blind source separation and has been received attention because of its potential application in signal processing, such as telecommunication and image processing. In this paper, the fundamental principle and algorithm of ICA are introduced. The feasibility of ICA for feature extraction is studied and a new method of handwriting character recognition based on the combination of ICA and neural networks is proposed. The experiment results show that ICA has good performance for feature extraction and this proposed method is more effective in recognizing handwriting character in comparison with the method based on neural networks directly. |
