todo: add sample ID of min and max values for inspection

[rbavery]

all statistics for each instance are in these csvs files. We can use the distributions here to decide on an area threshold

all_notile.csv
all_tiled.csv

[jonaraphael]

Hey Ryan--can you annotate what the units are for these tables? thanks!

[rbavery]

sure thing. They are all in pixel units. I can reflect that in the tables. conversion to meters would require associating the projection info to annotations which we haven't done yet and would take some time so I think for now we should stick to examining pixel units if you agree @jonaraphael

[rbavery]

To-do, update measurement to show moments or something closer to rotated bounding box lengths. rerun stats after @jonaraphael uploads natural seep scenes.
