SIK dataset #10

Closed llpspark closed 2 years ago

llpspark commented 2 years ago

hi， nice work for hand 3D. I wonder to know what's the relationship between SIK-1M and SIK-fh dataset, I just found SIK-fh have some large range pose compare to SIK-1M.

Thanks for you interest in our work ! If i remember correctly, the SIK-fh is the joint rotation-location pairs of the samples in freiHAND (''-fh'') dataset !

thank u for ur reply @lixiny @LyuJ1998 . and I wonder to know how to get the pose parameter(quat) ? generally, I think it maybe come from 48 dimensional (the first 3 dim is global rotation parameters) MANO pose vector in axis-angle representation minus the mean pose, and then convert to Quaternion represention, it just like the InterHand MANO annot: https://mks0601.github.io/InterHand2.6M/ , Is that right?

sional (the first 3 dim is global rotation parameters) MANO pose vector in axis-angle representation minus the mean pose, and then convert to Quat

Not necessarily need to minus the mean pose. It depends how the original MANO params are obtained.
