| 摘 要： | 针对纸币上常见的笔划及撕裂, 提出了一种基于均匀性特征的污损检测方法. 首先利用均匀性特征判定待检纸币上可能存在污损的区域, 然后进行图像配准, 确定这些区域在参考图像上的对应位置, 并逐像素进行比较, 最终判定待检图像的污损状况.

| Abstract: | This paper advances a homogeneity based algorithm for the detection of scratches and cracks appearing on paper currency. The homogeneity feature of the sensed paper currency image is first constructed to locate the possibly polluted pixels. The image registration algorithm is subsequently used to overlay the sensed and reference paper currency images. At last, each possibly polluted pixel on the sensed image is compared with its corresponding pixel on the reference image to estimate the contamination level. |
