Hi,
Thanks for your excellent work!

  • I noticed that the label in region classification task range from 0~12(e.g., train_room_pano_label.txt), what's the label's mean? I've thought it was the semantic category of the region (e.g., bedroom, kitchen, patio, etc.) ,but in data_organization.md, there should be 31 classes.

  • What's more, I wonder that what does the last two columns mean in panorama_to_region.txt, why line3 and line4 are both 'b' in last column, but one is 2 and the other one is 6 in penultimate column? And in different house the number in penultimate column is different for the same string?

About the first question, the 12 labels can be found in tab. 5 in the paper.
About the second question, the penultimate column is the region id.
