How to obtain the 'th_trans' values for the MANO model #17

Hi,

Great work! How do you obtain the 'hand_info['trans']' during annotation? To my knowledge, the translation vector of the hand should be a part of the 'theta' parameter. Did you also optimize this translation vector?

Hi Toytiny,

We have jointly optimized the translation vector and 48D rotations via the hand pose annotation process mentioned in our paper. Our loss functions are defined in Equation 1 and 2, and details are introduced in the appendix. Hope it can help you.
