| 摘 要： | 票据图象的准确分类检测是实现金融票据自动处理的基础。论文应用经典的数字图象处理理论,提出了一种新的多类别票据图象检测方法,即在原始票据图象利用模板匹配先得到相应的有效图象,再运用差影技术对滤波去噪后的有效图象进行模板存在与否的检测。实际的票据分类处理实验结果证实了所提出的方法的有效性。

| Abstract: | The correct detectio n and classification of bill image is the basis of realizing finance bill automati c process-ing.By use of classical digital image processing theory,a new mult i-sort bill image detection method is provided.The available image is found by template matching in original bill image.After the elimination of noise by fil ter,the image substraction is used to detecting the existence of template in av ailable image.The validity of method is proved by the experimental result of cl assification on many bill images. |
