【Abstract】 According to the concept of information fusion technique, a new handwritten digit recognition method based on neural networks and multi- structure information fusion is given. The four different compensated features are extracted from the char image and six fusion features are obtained from fusing these features. An optimized BP neural networks was applied to classify the pattern with the multi-features at first, then the neural networks is used to fuse the results derived from the six classifiers. The experiment results shows that the new algorithm can increase recognition rate effectively, and the system has higher system reliability.更多还原
