Bounding box of AFLW2000-3D

[HaoKun-Li]

Hi!
I am trying to calculate the NME of the AFLW2000-3D dataset. But I have no way to get the bounding box annotation from AFLW2000-3D. The "roi" information provided by the AFLW2000-3D dataset is strange. I think it is not the bounding box of faces.
Could you tell me how to get the bounding box annotation of the AFLW2000-3D dataset?
