Could you provide an explanation of parameters in params.py ?
See original GitHub issueHi ! 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 params.py ? 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.
Why there’s u_shp and u_exp separately？ What 's the meaning of u_exp here ?
