I'm talking about sold units in the field.

The same thing we always do. Pay some citizens of an African nation a pitiful wage to just make up annotations.

Then you can incorporate this into a "health care product" and charge insurance companies insane rates on personal toilet cameras.

I meant that they train their system on pictures where they have the underlying medical data. Their system might still be total crap (teehee), but I'm guessing that they at least try to make it predictive/generalized.
