众所周知，匹配陌生面孔的图像很容易出错。然而，实验室中的人脸匹配与现实环境中的人脸匹配之间存在严重的不匹配。目前所有可用的面部匹配数据库都是为了建立陌生面部感知的基线水平而设计的。因此，每个人脸身份的目标图像和测试图像都是在同一天拍摄的，从而最大限度地减少了人脸内部的变化。另一方面，在现实环境中，面孔确实会有所不同，甚至每天都会有所不同。这项研究检查了匹配陌生面孔图像的熟练程度，这些图像是在同一天或相隔几个月拍摄的。在两项实验中，使用标准的 1-in-10 和成对人脸匹配任务，当天的图像比不同日期的照片匹配得更准确、更快。这表明面部匹配的实验研究低估了其在现实世界中的难度。陌生面孔的照片似乎是不可靠的身份证明，特别是如果身份证件不使用持有人最近的照片。版权所有 © 2013 约翰·威利父子有限公司
It is well‐established that matching images of unfamiliar faces is rather error prone. However, there is an important mismatch between face matching in laboratory and realistic settings. All of the currently available face‐matching databases were designed to establish the baseline level of unfamiliar face perception. Therefore, target and test images for each face identity have been taken on the same day, minimizing within‐face variations. In realistic settings, on the other hand, faces do vary, even day to day. This study examined the proficiency of matching images of unfamiliar faces, which were taken on the same day or months apart. In two experiments, same‐day images were matched substantially more accurately and faster than different‐date photographs using the standard 1‐in‐10 and pairwise face‐matching tasks. This suggests that experimental studies on face matching underestimate its difficulty in real‐world situations. Photographs of unfamiliar faces seem to be unreliable proofs of identity, especially if the ID documents do not use very recent images of the holders. Copyright © 2013 John Wiley & Sons, Ltd.
