人民币纸币序列号、面额号定位与分割

The Location and Segmentation of Banknote Number and Denomination Number of RMB

随着经济的发展和繁荣,纸币的流通量越来越大,银行或其他金融机构常需要对序列号的信息进行采集,用于分类和防伪。在研究纸币图像的Sobel和Canny边缘检测结果和纸币本身的特点以后,提出基于边缘检测和投影法的三步序列号分割方法,即序列号所在左侧区域的定位、序列号与面额号所在区域的准确定位、序列号与面额号的辨别与分割三个步骤。还对纸币的面向和倒置与否进行识别,使得算法可以应用于更为复杂的情况。

With the development and prosperity of economy,the circulation of paper currency is growing rapidly.The banknote numbers are always collected for classifying the bankbill and identifying the counterfeit ones.After studing on the edge detection results of Sobel and Canny algorithms,a new banknote number segmentation method based on edge detection and projection is presented,which can be devided into three steps-the location of the area on the left of the serial numbers,the location of the area that the serial number and the denomination number located,the identification and segmentation of the serial number and the denomination number.The front versus back,as well as inversion,are also studied in the dissertation.
