Some questions about ASH #8

Hi! Thank you for your excellent work! I am a newbie of 3D Vision. May I ask some questions about the paper?

  1. In Sec. 3.2, whether the $w{(·),i}$ in formula(4) are learnable parameters? In other words, how could we get the $w{(·),i}$?
  2. In Sec. 3.3, I am not sure how could we get $$\boldsymbol{\mu}{uv, i}^{\prime \prime}$$ from the texture texels of the pose-deformed template mesh $$\boldsymbol{\mu}{uv, i}$$. Could you offer more information about this operation? (Besides, I think there is a typo, the pose-deformed template mesh is $$Vf$$, not $$\boldsymbol{\mu}{uv, i}$$). To be honest, I can not understand operations of the warmup stage. Sorry to bother you, thank you very much!
