Range of depth?

What is the range of depth predictions?

https://github.com/1adrianb/2D-and-3D-face-alignment/blob/c85491111758e459a42fe9c903f26d990043582c/main.lua#L78

Thanks in advance!

The issue asks about the range of depth predictions in the linked Lua code line. Look at main.lua around line 78 to see how depth predictions are computed or normalized. Check if there are comments, constants, or related functions that define the range. Answering likely requires understanding the model's output scaling or reading the paper referenced in the repository description.
