我们经常使用面部图像来识别人。在护照检查等职业环境中以及在日常社会环境中，情况都是如此。图像和身份之间的映射假设面部外观在一定范围内是稳定的。例如，一个人的表面年龄，性别和种族变化缓慢，如果有的话。它还假设故意改变这些界限（即，伪装）很容易被发现。超逼真的面具颠覆了这些假设，让佩戴者看起来像一个完全不同的人。如果不被注意，这些面具打破了面部外观和个人身份之间的联系，对应用面部识别有明显的影响。然而，迄今为止，还没有人对这些面具的真实性进行评估，也没有人具体说明在什么条件下它们可以被接受为真实的面孔。在这里，我们研究了意外的意外检测，但出席超现实的面具在摄影和现场演示。实验1（联合王国; n = 60）没有发现在真实的面部照片中明显检测到超现实面具的证据，并且几乎没有隐蔽检测的证据。实验2（日本; n = 60）扩展这些发现不同的面具，面具佩戴者和参与者池。在实验3（英国和日本; n = 407），路人没有注意到，一个活的同盟者戴着一个超现实的面具，并显示出有限的证据隐蔽检测，即使在近距离观看（5与20米）。在所有这些研究中，观众接受了超现实的面具作为真实的面孔。如果要提高侦查率，就需要采取具体的对策。本文的在线版本（doi：10.1186/s41235-017-0079-y）包含补充材料，可供授权用户使用。
We often identify people using face images. This is true in occupational settings such as passport control as well as in everyday social environments. Mapping between images and identities assumes that facial appearance is stable within certain bounds. For example, a person’s apparent age, gender and ethnicity change slowly, if at all. It also assumes that deliberate changes beyond these bounds (i.e., disguises) would be easy to spot. Hyper-realistic face masks overturn these assumptions by allowing the wearer to look like an entirely different person. If unnoticed, these masks break the link between facial appearance and personal identity, with clear implications for applied face recognition. However, to date, no one has assessed the realism of these masks, or specified conditions under which they may be accepted as real faces. Herein, we examined incidental detection of unexpected but attended hyper-realistic masks in both photographic and live presentations. Experiment 1 (UK; n = 60) revealed no evidence for overt detection of hyper-realistic masks among real face photos, and little evidence of covert detection. Experiment 2 (Japan; n = 60) extended these findings to different masks, mask-wearers and participant pools. In Experiment 3 (UK and Japan; n = 407), passers-by failed to notice that a live confederate was wearing a hyper-realistic mask and showed limited evidence of covert detection, even at close viewing distance (5 vs. 20 m). Across all of these studies, viewers accepted hyper-realistic masks as real faces. Specific countermeasures will be required if detection rates are to be improved.
