About 3D faces the Bosphorus database

[Elena Battini]

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.

Regards, Idil

Hi Idil 

ihope that you find a solution to bnt file of  Bosphorus database 

Can you help me plot and mesh the 3D face 

Thankfully

Hi,

I attached Code to convert bnt flies to off. See the file bnt2OFF for an exmple
