Thank you for your excellent work. I have some questions and uncertainties regarding this project.

  1. Could you please clarify what coordinate system is specifically referred to as 'canonical' mentioned below?
    And I am not sure about the meaning of R0 and T0. The highest dimension of R0 and T0 is 1, so I guess that it's the pose of the egocentric camera in the world coordinate system for the first frame of seq.

  1. Please explain what "articulation" specifically refers to as a variable and its exact meaning.

  2. As shown in the image below, each part of the object has one 3d bbox and 16 3d kpts.
    I noticed that scripts_data/process_seqs.py seems to output bbox3d and kp3d, but scripts_data/visualizer.py does not seem to display them.

Thanks a lot!
