| 摘 要： | 该文为解决计算机对打印文档的自动鉴别与检索问题，研究激光打印机的工作机理，以器件特性反映到打印图形中的差异做为打印文档鉴别与检索的依据。设计一种新的双极性Hausdorff距离用于有效的一对一打印字符匹配，之后综合样本的所有字符，采用字符集匹配计算二次距离进一步提高打印图形鉴别和检索的准确性。实验表明该方法能够取得较为理想的效果，其中检索正确率为90%，鉴别最小错误率为17.80%。 |

| Abstract: | In this paper laser printer mechanism is researched, and intelligent print document identification and retrieval are achieved by measuring print shape deviation which reflects the intrinsic tolerances of printer device. A novel polar Hausdorff distance is proposed to obtain effective performance of the print shape matching. Print character set including all samples is applied to compare and improve the identification and retrieval accuracy. Experimental results show the approach is suitable for this application in which the accuracy is 90% for retrieval and the minimum error rate is 17.80% for identification. |
| Keywords: | Image match Document identification and retrieval Polar Hausdorff distance |
