信息技术——生物特征学——指纹数据库技术评价难度的表征与度量

[中文适用范围]： 本技术报告根据相对样本质量、相对旋转、变形和印象之间的重叠来估计指纹识别评估数据集的“挑战性”或“压力”程度。 此外，本技术报告还建立了不同难度级别数据集的构建方法。 本技术报告定义了指纹识别算法技术评估中使用的指纹数据集的相对难度级别。 难度级别基于参考样本和探针样本在上述因素中的差异。 本技术报告解决了以下问题： ——表征从同一手指获取的样本之间的差异所导致的难度水平， — 开发统计方法，通过汇总影响因素来表示指纹数据集的难度水平， — 比较指纹数据集的难度水平不同的指纹数据集， — 定义测试和报告为技术评估而收集的指纹数据集的难度级别的程序， — 根据比较分数分析配对数据特征， — 描述用于构建评估数据集的存档数据选择方法。 [外文原描述]： ISO/IEC TR 29198:2013 provides guidance on estimating how "challenging" or "stressing" is an evaluation dataset for fingerprint recognition, based on relative sample quality, relative rotation, deformation, and overlap between impressions. In addition, it establishes a method for construction of datasets of different levels of difficulty. It defines the relative level of difficulty of a fingerprint dataset used in technology evaluation of fingerprint recognition algorithms. Level of difficulty is based on differences between reference and probe samples in the aforementioned factors. ISO/IEC TR 29198:2013 addresses such issues as: characterizing level of difficulty attributable to differences between samples acquired from the same finger, developing statistical methodologies for representing the level of difficulty of a fingerprint dataset by aggregating influencing factors, comparing the level of difficulty of different fingerprint datasets, defining procedures for testing and reporting the level of difficulty of fingerprint datasets collected for technology evaluation, analysing mated pair data characteristics based on comparison scores, describing the archived data selection methodology for building a dataset for evaluation. It provides guidelines for comparing the relative level of difficulty of fingerprint datasets. Outside the scope of ISO/IEC TR 29198:2013 are: defining the quality of individual fingerprint images, defining the methodologies or explicit measures for evaluating or predicting the performance of fingerprint recognition algorithms.
