One of the values it returns is the ID number of face detected
correct. (that was simple)
the other value it returns (conf)
that's not so simple. it''s the (L2) distance to the nearest image in the database, it's more the opposite of a "confidence" (less is better) and it'S entirely non-linear, so you won't find an easy formula to make it a percentage or such.
lies in range 1000 to 2000
that's arbitrary, it depends on your local database.
in the end, you'll probably set a threshold value from the worst true and the best false recognition.
