摘要:

在本文中,我们提出了无约束的耳朵识别挑战(UERC)的结果,一组基准测试的努力,围绕在不受控制的条件下捕获的耳朵图像的人识别的问题。该挑战的目标是评估现有耳朵识别技术在具有挑战性的大规模数据集上的性能,并确定未来需要解决的开放问题。来自三大洲的五个小组参加了挑战,并为评估提供了六种耳朵识别技术,而UERC组织者为挑战提供了多个基线。对所有参与方法进行了全面分析,解决了与头部旋转,翻转,画廊大小,大规模识别等技术的敏感性有关的基本研究问题。研究发现,UERC的最佳表现者在数据集的一小部分(180名受试者)上确保了稳健的性能,而不管图像特征如何,但当使用包括3,704名受试者的整个数据集进行测试时,仍然表现出显著的性能下降。

英文摘要:

In this paper we present the results of the Unconstrained Ear Recognition Challenge (UERC), a group benchmarking effort centered around the problem of person recognition from ear images captured in uncontrolled conditions. The goal of the challenge was to assess the performance of existing ear recognition techniques on a challenging large-scale dataset and identify open problems that need to be addressed in the future. Five groups from three continents participated in the challenge and contributed six ear recognition techniques for the evaluation, while multiple baselines were made available for the challenge by the UERC organizers. A comprehensive analysis was conducted with all participating approaches addressing essential research questions pertaining to the sensitivity of the technology to head rotation, flipping, gallery size, large-scale recognition and others. The top performer of the UERC was found to ensure robust performance on a smaller part of the dataset (with 180 subjects) regardless of image characteristics, but still exhibited a significant performance drop when the entire dataset comprising 3,704 subjects was used for testing.
