摘要:

指纹识别系统的典型评估包括端到端黑盒评估,其评估总体识别或认证准确性方面的性能。然而,这些系统性能的黑盒测试没有揭示对各个模块的性能的洞察,包括图像采集、特征提取和匹配。另一方面,白盒评估,本文的主题,衡量单独的每个组成模块的性能。虽然一些研究已经对指纹读取器、特征提取器和匹配组件进行了白盒评估,但是没有现有的研究提供对在指纹识别系统的每个阶段引入的不确定性的完整系统的白盒分析。在这项工作中,我们扩展了以前的白盒评估的指纹识别系统组件,并提供了一个统一的,深入的分析指纹识别系统性能的基础上,汇总的白盒评估结果。特别地,我们分析了由于不利的捕获条件(即,改变照明、湿度和压力)。我们的实验表明,在黑盒识别性能方面整体表现更好的系统不一定在指纹识别系统流水线中的每个模块处表现最好,这只能通过对每个子模块的白盒分析来看到。诸如此类的发现使研究人员能够更好地集中精力改进指纹识别系统。

英文摘要:

Typical evaluations of fingerprint recognition systems consist of end-to-end black-box evaluations, which assess performance in terms of overall identification or authentication accuracy. However, these black-box tests of system performance do not reveal insights into the performance of the individual modules, including image acquisition, feature extraction, and matching. On the other hand, white-box evaluations, the topic of this paper, measure the individual performance of each constituent module in isolation. While a few studies have conducted white-box evaluations of the fingerprint reader, feature extractor, and matching components, no existing study has provided a full system, white-box analysis of the uncertainty introduced at each stage of a fingerprint recognition system. In this work, we extend previous white-box evaluations of fingerprint recognition system components and provide a unified, in-depth analysis of fingerprint recognition system performance based on the aggregated white-box evaluation results. In particular, we analyze the uncertainty introduced at each stage of the fingerprint recognition system due to adverse capture conditions (i.e., varying illumination, moisture, and pressure) at the time of acquisition. Our experiments show that a system that performs better overall, in terms of black-box recognition performance, does not necessarily perform best at each module in the fingerprint recognition system pipeline, which can only be seen with white-box analysis of each sub-module. Findings such as these enable researchers to better focus their efforts in improving fingerprint recognition systems.
