What is the range of depth predictions?

Thanks in advance!

Hi @ablavatski, I don't remember the exact range but at that point expect values in the range [-70, 70] approximatively. The depth predicted should be consistent with the one from the 3DDFA model if you zero mean it. If you need a more accurate range let me know and I will check it.

Hi @1adrianb I can't check the model cause I use Ubuntu and the code for the model is written for Windows. Could you check the range for me and tell me what I need to do after this depth_pred*(1/(256/(200*fileList[i].scale))) in order to have values in a range [-1, 1]. Thank you in advance.
