最近在DNA证据处理方法上的进步已经开始迫使人们更仔细地审查关于其他种类证据的强度的断言。传统的证据来源之一是指纹。目前，从嫌疑犯身上提取的指纹与犯罪现场的痕迹进行比较，然后由专家根据匹配的细节和这些细节周围的脊线模式进行判断，宣布匹配。然而，这些方法已证明难以有效量化。这引起了对印刷品和商标中更细微特征的研究。这些特征中的一组是沿着指纹的脊定位的许多孔。是否有可能根据孔隙信息，用更自动和定量的证据强度测量来补充与匹配相关的专家判断？初步分析的结果表明，我们可以。我们的方法是相对透明的，使用共同的统计数据进行两个样本的点模式比较。这里讨论的结果涉及匹配的墨打印使用灰度成像和补充以前的研究，往往侧重于比较二值化图像。
Recent methodological advances in the processing of DNA evidence have begun to force a closer examination of assertions about the strength of other sorts of evidence. One traditional source of evidence is the fingerprint. Currently a print taken from a suspect is compared against a mark from a crime scene and a match declared using the judgement of an expert based on matching minutiae and the ridge patterns around these. However, such methods have proved difficult to quantify effectively. This has provoked the investigation of even finer features in the print and the mark. One set of such features are the many pores, located along the ridges of the fingerprint. Is it possible to supplement expert judgements associated with a match with a more automatic and quantitative measure of the strength of evidence, based on pore information? The results of this preliminary analysis suggest we can. Our methodology is relatively transparent, using common statistics for two sample comparisons of point patterns. The results discussed here concern the matching of inked prints using grey-level imaging and complement previous studies which tend to focus on the comparison of binarised images.
