AI总结:

本研究通过扩展的真实世界退化流程,分析单一与组合退化对人脸识别模型的影响,发现组合退化即使单一影响可忽略也会显著降低性能,强调评估模型鲁棒性需考虑真实复杂性。

摘要:

人脸识别模型通常在受控环境中收集的大型图像数据集上进行训练。由于干净图像与真实环境图像之间存在域差距,这导致模型应用于真实场景时出现性能差异。因此,一些研究人员通过分析合成退化来研究这些模型的鲁棒性。然而,现有研究多聚焦于单一退化因素,可能无法充分捕捉真实世界退化的复杂性。本研究通过使用扩展了欠曝光/过曝光条件的真实世界退化流程,分析单一和组合退化的影响来解决这一问题。我们使用 LFW 数据集进行实验,并基于验证准确率评估模型性能。结果表明,单一和组合退化表现出不同的模型行为。即使单一退化的影响可以忽略不计,组合退化的效应也会显著降低性能。本研究强调了考虑真实世界复杂性以评估真实环境中人脸识别模型鲁棒性的重要性。代码公开于 https://github.com/ThEnded32/AnalyzingCombinedDegradations。

英文摘要:

A face recognition model is typically trained on large datasets of images that may be collected from controlled environments. This results in performance discrepancies when applied to real-world scenarios due to the domain gap between clean and in-the-wild images. Therefore, some researchers have investigated the robustness of these models by analyzing synthetic degradations. Yet, existing studies have mostly focused on single degradation factors, which may not fully capture the complexity of real-world degradations. This work addresses this problem by analyzing the impact of both single and combined degradations using a real-world degradation pipeline extended with under/over-exposure conditions. We use the LFW dataset for our experiments and assess the model's performance based on verification accuracy. Results reveal that single and combined degradations show dissimilar model behavior. The combined effect of degradation significantly lowers performance even if its single effect is negligible. This work emphasizes the importance of accounting for real-world complexity to assess the robustness of face recognition models in real-world settings. The code is publicly available at https://github.com/ThEnded32/AnalyzingCombinedDegradations.
