Research of coins identification based on neural network

The technology of neural network image recognition is a kind of new-style image recognition technology,which is developed due to the theory of present computer technology,image processing,artificial intelligence and pattern recognition.According to the research to several familiar coins image,six feature functions which describe many kinds of coins roundly are proposed in this article.BP network based on the matlab is founded,and then the coin recognition is realized.Experience results show that the method which is proposed in this article can recognize different kinds of coins and the recognition process is fast,simple and convenient.
