Research on the Recognition of Paper Currency Number With Low Resolution
Xiwen Liu, Chaoying Liu · 2015
According to the characteristics that the paper currency image has low resolution and it is vulnerable to noise affect, the methods of paper serial number region extraction and segmentation are discussed, and multi-level 2DPCA algorithm is used for serial number recognition.Experiment results show that the methods proposed in this paper have the advantages of fast speed, high recognition accuracy and good anti-interference ability.
