Question about number of region_spatial features

[czy-orange]

Hi @bearcatt,
Thanks for your sharing code. I met one problem here spatial_region, what are the 5th and 6th first feature about (region_spatial [:,:,[5,6])?
Moreover, from your paper there are five (four for location coordinate and one for relative area) in localization feature(in implementation details section), but in your code here there are six features in last dimension. Can you help me understand this part?
