Wenhong Li, Yonggang Li, Luo Kexue · 2008
The processing effect and recognition accuracy of RMB is an important part in the paper currency classification system. According to the characteristics of RMB images, the paper uses the theory of digital image processing and pattern recognition to put forward the method of RMB image processing based on the processing and recognition of the part of the RMB serial numbers, the arithmetic of linear perception based on rewards and punishment method and the extraction method of serial numbers character. Through the experiment on the paper currency classification system which uses the CIS sensor as the image acquisition, it testifies that this method of recognition has a high feasibility and recognition accuracy.
