摘要
目的通过研究抽取笔压特征的方法为签名笔迹鉴定提供有效的检验手段。方法为了将笔压特征脱离其他特征而突显出来,通过实验考察了多种显现方法,包括体视显微镜侧光观察法、侧光红外影像法、静电压痕显现法、显微图像三维重建法和激光共聚焦扫描显微镜法。结果比较多种方法所获得的显现结果,实验表明五种方法在展现笔压特征上各有优缺点。结论笔迹鉴定人员应该充分利用可获得的多种手段分析笔压特征,来提高签名笔迹鉴定意见的可靠性。
Objective To establish effective methods of extracting pen pressure features for the identification of signatures. Methods To portray pen pressure apart from other handwriting features, five methods were experimentally investigated, includ- ing stereomicroscopy with oblique lighting, infrared imaging with oblique lighting, electrostatic detection apparatus, three-di- mensional reconstruction and confoeal laser scanning microscopy. Results Each of the five methods has advantages and disad- vantages. Conclusion Questioned document examiners should use as many approaches as possible to utilize the pen pressure features, so as to improve the reliability of the signature examination results.
