基于知识的印鉴鉴别方法

计算机印鉴鉴别是一项十分困难但又具有广泛应用背景的课题,国际上至今尚无实用有 效的鉴别方法.本文从知识工程的角度出发,对印鉴鉴别中的启发式知识进行了深入的讨论. 并在此基础上引入了一套完整的基于启发式知识的印鉴鉴别方法.该方法以启发式搜索获得 配准关系,并根据启发式知识在其中提取一组结构特征,最后结合结构信息和统计模型作出判 决.实验结果表明,该方法在可靠性、适应性和实用性方面比现有方法均有明显改进,已接近 实用.

A Knowledge Based Seal Imprint Verification Approach

To verify seal imprint by computer is a difficult practical problem. There is no efficient and practical approach up to date. According to the ideas of knowledge engineering and concepts of tne heuristic knowledge in the seal imprint verification, an effective and practical approach has been presented in this paper. In the approach, heuristic search scheme is used to calculate the registration relation, several effective features are extracted based on heuristic knowledge, and final decision is made in a statistical classification model with structural information. Extensive experiments show that this approach is superior in reliability, adaptability and practability to many existing approaches.
