v2 and v1 of this dataset had no info on region centers. The habitat version of the original matterport data does

[rishiswethan]

Thanks for your excellent work. Due to the lack of center coordinates, I am not able to extract the images from all regions of a scene for semantic segmentation. When I use the habitat version of the original matterport dataset that is downloaded from download_mp.py, it has the centers of regions. Is there any other way to get centers, or to get all regions somehow without the center?

I tried doing things like using the coords door, ceiling, etc to find a center, but all were bad, as I couldn't point to which direction it should move, in order to reach the center. I think a workaround would be to detect all walls and ceilings, then compute the centers that way, but I doubt this will work for all images. Is there any other workaround?
