Can you give examples of what you observe? The pose parameters we regress for HaMeR should be directly compatible with the hand pose parameters that SMPL-X expects as input. Is the problem happening with both hands or only with the left hand? If it's the second, you might need to mirror the parameters (left-right flipping).
https://github.com/geopavlakos/hamer/assets/63392592/7a2b2643-994d-462b-9a20-c465f88fe22f Thank you for your reply! It indeed seems to be with problem in the left hand. so how should I flip the mano parameters for the left hand?
Actually, the right hand doesn't look correct either. Could you try again by setting the flag flat_hand_mean=True
?
Regarding flipping, you can convert the rotation matrices to axis angle and then for each joint rotation, you will need to multiply the second and the third element by -1 (see also how we do it in our code here).
same error, I multiply the second and the third element by -1 with ['pred_mano_params']['hand_pose'] and copied into SMPLH, but the left hand still with problem. " convert the rotation matrices to axis angle" is indeed? how can i flip the mano parameters without the rotation matrices to axis angle?
Great work! I'd like to know how to convert the MANO parameters obtained from Hamer into the hand pose of SMPL-X. Directly replacing them results in odd effects.
