about face model data

Hi,jianzhu,
how to obtain Model_Expression.mat in the face profiling code？ is it the part of BFM model?
I am looking forward to your reply, thank you!

You can refer to face3d to get the Model_Expression.mat.

Hi, jianzhu,
thanks for you relpy!
I found YadiraF/face3d also copy the 3DDFA/Model_Expression.mat to BFM/3ddfa folder:
as shown in the following code: https://github.com/YadiraF/face3d/blob/master/examples/Data/BFM/generate.m
% 2. load expression
load('3ddfa/Model_Expression.mat');
model.expMU = mu_exp;
model.expPC = w_exp;
model.expEV = sigma_exp;
how can generate this Model_Expression.mat?
and whether the pose, shape, expression parameters of the 300W_LP dataset are generated by 3DMMFitting matlab code?
I am looking forward to your reply, thank you first!

hi, do you know the answer now?

[niannianmeng]

no, i still don't know how to get the shape,expression parameters of images like 300W_LP.

[ReverseSystem001]

 the D of the shape,expression parameters are corresponding to the BFM09 shape,expression Base.the paper of 3DDFA says it generated by face profiling.

face profiling can augment the data of 300W_LP, but I don't know how to obtain the shape, expression parameter of 300W_LP

@cleardusk Can you explain quickly how to generate Model_Expression.mat ?

In the FaceWarehouse paper, the expresion parameters is 47, and your Model_Expression.mat is 29 dimensions.

Thanks
