Difference between new_params_neutral and new_params #37

Closed greatbaozi001 closed 3 months ago

Hellow! In the Thuman dataset, it seems that one can generate SMPL vertices by either loading from new_verttices or calculating from new_params_neutral or new_params. What's the different among these three kind of method for loading SMPL vertices?

skhu101 commented 3 months ago

Hi, new_params are estimated for male or female gender, while new_params_neutral are estimated for neutral gender.

Thanks for your reply! Actually there is a tiny difference between the vertices generated by new_vertices_neutral and the one direclty loaded from new_vertices, which cause the difference?

skhu101 commented 3 months ago

Hi, parameters in SMPL models with different genders are different. So the generated vertices have a tiny difference.

Sorry that I am still a kind of confused. Now I understand that new_params and new_params_neutral are different as they are estimated for male / female gender or neutral gender. I wonder how the new_vertices were calculated, as I found that there is a slightly difference between new_vertices and the one calculated from either new_params or new_params_neutral.
