Estimated pose labels of the three images in Pointing04 from 13 different observers by rotating a 3D head model. We can see that large standard deviations exist for these labeled ground truths.

1. Makeup greatly affects observed age2. Living condition affects observed age3. An integer age l means the age within [l, l+1)4. Without ground truth, the age estimation is subject-dependent

Label is Uncertain and Nonnegative !!!

Pose Estimation

Age Estimation
