some questions about my implementation #23

Hi, @mattpoggi, Thanks for your excellent work!! I have some questions about my implementation.

  1. In the depth decoder (S), it is output 4 scale disparity and uncertainty, I would like to know that have you calculated all scale outputs when you implemented eq.14? image

  2. If my uncertainty has some negative values, Should I limit it to>0?

Hi @Bowwowlol,

  1. depth and uncertainty at each scale are upsampled to full resolution when computing the loss
  2. if you assume your output uncertainty is u=log(uncertainty), you should be fine (then replace sigma with exp(u) in the loss function)
