How can it work without the 'I' information?

Hello, thanks for a such a great repository!

I have one question, how can the create_uv_texture_from_image_by_using_densepose.py script work without the part information? If I understand correctly, the original IUV formulation generates outputs two type of data: the UV coordinates of each body part (of range 0,1), and the body part (of range 1-24) that specifies a what body part (or island of the UV map) each pixel corresponds.

My question is, the script create_uv_texture_from_image_by_using_densepose.py only requires a .jpg with the dense correspondences but in that file there is not information about the body part (what is originally refers to I in the DensePose formulation). I don't see how it can manage to produce the final texture. Could you share some details? I looked at the source code but couldn't find the underlaying logic.

Thanks!
