Dear all, I am a researcher interested in working with 3D faces; I obtained access to the Bosphorus 3D face database. In its last version the database has:
  • "filename.bnt”: storing the 3D coordinates with corresponding 2D image coordinates. On the web page, is written: data format is like 3D coordinate map of the acquired 2D images over the segmented regions; wireframe meshes are not available.
  • “filename.png”: color image file
  • “filename.lm2”: 2D landmark file with the corresponding labels
  • “filename.lm3”: 3D landmark file with the corresponding labels
  • A Matlab function to read the “bnt” files is provided.
Using the given MATLAB function, I open the bnt file and I reach “data”, which is a matrix of size (41625*5) of doubles; the size of every image is 225*185=41625.
As far as I understand, I need a function to create wireframe meshes so as to be able to see the 3D faces and plot their face landmarks (lm3) on the top of them.
I would really appreciate if you could direct me in this issue. Thanks in advance, Idil

Hi Idil,
Did you have any luck about this issue? I'm trying to do same on Bosphorus Database.

Unfortunately, I could NOT manage to use that database ... There is also the big problem that all values are very little; probably, they have been normalized and we are supposed to bring them back to their original range ... It is a shame to have a database but no any documentation about it!!!
Other 3D face database? FRGC v2: I could not manage to have it. It is probably not in use anymore BU-3DFE: Binghamton University 3D facial Expression. For sale.
Cheers, Idil
