Serial Number Idenfication of RMB Banknote Based on Neural Network
Yu Tu · 2011
Research RMB intelligent identication problem.The serial number of RMB is its card,but in circulation process,RMB is prone to be worn and polluted,so the identification accuracy of RMB serial number is not high.In order to improve the accuracy of RMB serial number identification,a RMB serial number identification algorithm was proposed based on BP neural network.Firstly,RMB images were pretreated and eliminated to erase the noise information,then RMB serial number was segmentation and normalized.Then the character characteristic vector was extracted,and BP neural network was used to recognize the characters.Simulation results show that the recognition rate of BP neural network can reach 97%,and the identifying time is short,which can meet the requirements of RMB serial number identification very well.
