Abstract

Abstract: In order to enhance the accuracy in bill recognition, the bill location was studied. A new locating technique based on structure was proposed in this paper. It used the number and the relative position of intersecting points on the main margin of checks as the structural feature of the check, classified the bills with the similarity functions we defined, and extracted the recognition region of the bill at last. The experimental results demonstrate that this algorithm works well in bill location.

Key words: bill recognition, feature extraction, similarity function

摘要： 为了提高票据识别的准确率，对票据定位进行了研究。提出了一种基于结构的定位方法。它利用票据主边框上交叉点的个数和相对位置作为票据的特征信息，并将这些信息通过相应的分类相似函数集与已定义的模版进行匹配，从而实现对票据的分类，最终提取出当前票据的识别区域。实验结果表明:该算法取得了很好的定位效果。
