What is the differences between face region mask (in paper cut) and 3d mask?

[betulays]

Hi,

Most of the file names given in the json files are not found in the dataset. Around 161k file names are in the json files but the rest do not exist. Could you help me about this issue?

Secondly, what is the differences between region mask and 3d mask. Can we accept face region mask as 3d attack? (Just I want to learn your opinion)

Thank you.

• We do unrelease part of our test data. Because we want to use that part of the data for the challenge. And, the results in the paper based on the test data which we have already released.

Secondly, what is the difference between region mask and 3d mask. Can we accept face region mask as 3d attack?

• The difference is whether the eye region/mouth region has been cropped.

@Davidzhangyuanhan 您好，关于3Dmask的数据，方便分享一下制作方式吗？ 我看了数据集里的图片，是不是先打印二维的彩色图片然后手工折成贴近人脸的形状，我看到鼻子部分很突出，是怎么处理的？
