What is the corresponding relationship between the vertices of BFM 2009 and BFM 2017 #11

Hello, I want to convert my vertices of BFM 2009 to the BFM 2017, is there a corresponding relationship between the vertives of BFM 2009 and BFM 2017? How can I align the 68 landmarks in BFM 2009 to the landmarks in BFM 2017? Is there an index file? thx :)

Thank you for the work of the author team. I have a similar question, can you answer it?

@thogerig @Andreas-Forster I think the two of you have built the BFM2017. Do you know if there exists a corresponding index file?

I do not know if this index file exists (or even existed somewhen), I guess not. I can not remember all the details, but I think the reference is mostly the same mesh, but there are some difference. There is the mouth interior, the mask is selected a bit differently and not sure if only the pose or the form has changed slightly. I have however no access to all the data anymore.

I think even for 68 landmarks it is fastest to transfer them by hand checking the triangulation. If you have way more landmarks, then I would register the two meshes onto each other, and accept that it might not be a perfect mapping but a very good one.
