Is it a fair comparison with others if you use gt focal length in your evaluation?

Hi, I wonder if it is a fair comparison with others if you use groundtruth focal length in your evaluation. This means you've known human size in test time and you do not consider the error introduced by the ambiguity of size ? Thanks.

Agree with @gdwei. As far as I know, no other published 3D pose estimation methods before this work use the GT camera parameters or GT root depth, while this one used both.

Hi @gdwei, @John6333, where did you see they use the ground truth focal length? Could you point me to where it is in the code?

Hi @VGonzalez88, please check this function, especially line623~637.
