摘要:

现有的人脸识别数据集通常缺乏遮挡样本,这阻碍了人脸识别的发展。特别是在COVID-19冠状病毒疫情期间,戴口罩已成为防止病毒传播的有效手段。在现有数据集上训练的传统基于CNN的人脸识别模型对于严重遮挡几乎无效。为此,我们开创了一个模拟遮挡人脸识别数据集。特别是,我们首先收集各种眼镜和面具作为遮挡,并随机组合遮挡属性(遮挡对象,纹理和颜色),以实现大量更逼真的遮挡类型。然后我们用正常遮挡习惯将它们覆盖在人脸图像的适当位置。此外,我们合理地结合原始正常的人脸图像和遮挡的人脸图像,形成我们的最终数据集,称为Webface-OCC。它涵盖了10,575名受试者的804,704张人脸图像,具有多种遮挡类型,以确保其多样性和稳定性。在公共数据集上进行的大量实验表明,由我们的数据集重新训练的ArcFace显着优于最先进的。Webface-OCC可在https://github.com/Baojin-Huang/Webface-OCC上获得。

英文摘要:

The existing face recognition datasets usually lack occlusion samples, which hinders the development of face recognition. Especially during the COVID-19 coronavirus epidemic, wearing a mask has become an effective means of preventing the virus spread. Traditional CNN-based face recognition models trained on existing datasets are almost ineffective for heavy occlusion. To this end, we pioneer a simulated occlusion face recognition dataset. In particular, we first collect a variety of glasses and masks as occlusion, and randomly combine the occlusion attributes (occlusion objects, textures,and colors) to achieve a large number of more realistic occlusion types. We then cover them in the proper position of the face image with the normal occlusion habit. Furthermore, we reasonably combine original normal face images and occluded face images to form our final dataset, termed as Webface-OCC. It covers 804,704 face images of 10,575 subjects, with diverse occlusion types to ensure its diversity and stability. Extensive experiments on public datasets show that the ArcFace retrained by our dataset significantly outperforms the state-of-the-arts. Webface-OCC is available at https://github.com/Baojin-Huang/Webface-OCC.
