摘要
本文提出了一种对纸币号码定位分割的方法。该方法针对采集来的纸币号码灰度图像,先进行总体阈值分割,使用水平投影和垂直投影对每个字符进行初步的定位,再对每个字符块区域进一步细化分割,实现对纸币号码的清晰准确的分割和定位,成功降低了由于纸币局部污迹对个别字符所造成的分割、识别不准确的影响。
This paper introduces a paper currency number segmentation and positioning method. For the acquired paper currency number gray image, first, do overall threshold segmentation, using horizontal and vertical projection for initial positioning each charac- ter. Then further refine the segment fast region of each character to realize the clear and accurate segmentation and positioning. Suc- cessfully reduce the inaccurate efiCect of segmentation and recognition due to partial stain on individual character notes.
