| 摘 要： | 提出了一种根据差值图像的线段参数进行印章识别的方法．首先完成目标图像与模板图像的精配准，然后对图像进行差值计算，用霍夫变换得到差值图像的直线段数．并用此直线段数作出判决．实验结果表明，利用该算法进行识别时正确性高，且所用时间短，效果好．所提供的方法在对6类目标60幅图像进行识别时总识别正确率高于85％．

| Abstract: | The authors propose a scheme for the seal imprint verification with the line parameter in difference matching image. The method can be used to match two images accurately. Then with Hough Transform, the authors calculate the number of beeline in difference matching image, at last they make the technique in the recognition experiments of 60 pieces final decision by the parameter. The performance of image, which gained from 6 kinds of objects, is also involved. The experiment result is satisfactory, which the correct-ratio of object recognition is above 85%. |
