Data prerocessing - zero-centering data around hip joint
Closed this issue · 3 comments
It is mentioned in the paper in the data preprocessing section that "since we do not predict the global position of the 3d prediction, we zero-center the 3d pose around the hip joint"
I don't understand how and where is that done in the code? Does this also need to be done for the 2d predictions?
Thank you!

You could, but we do not do that
Thank you for your response.
I got the 3d coordinates.. However I was expecting to get the Hip coordinates to be (0,0,0) since it is supposed to be centered around the hip, yet it isn't. Still a little lost as to what reference system is used to calculate the 3d coordinates? I probably need to manually call this function to obtain coordinates that are centered around the hip, but if I don't. what is the (0,0,0) point in this case.
