Could you provide an explanation of parameters in ?

See original GitHub issue

Hi ! Thanks for your amazing work. I’d like to use it as a base for further works. Could you please provide an explanation for the numpy matrices loaded in ? In particular:

  • Keypoints
  • w_shp
  • w_exp
  • u_shp
  • u_exp

I could be wrong but I am under the impression that these are base mesh data that are then deformed by the network’s prediction.

Thanks a lot for your help !

It is the 3DMM basis constructed by PCA, the original shape is 159645x199 but I remove the last 159 dimensions to perform acceleration, which has little effect on the reconstructed face.

U are right, w_shp and w_exp are the shape and expression basis; u_shp and u_exp are the mean.

Why there’s u_shp and u_exp separately? What 's the meaning of u_exp here ?
