gt_transl in process_data in process_arctic.py #23

Shouldn't gt_transl and T0 be the same?

If the global orientation of both the object and hand are with respect to camera coord space, then the object cano space and MANO cano space are different than the camera coord space by only a translation component.

Also, shouldn't targets["mano.j3d.full.r"] and targets["mano.j3d.cam.r"] be the same since both are in camera coord space?

targets["mano.j3d.full.r"] is the MANO joints in the original image coordinate (full resolution image). targets["mano.j3d.cam.r"] is in the coordinate of cropped image with the bounding box.
