nice, how about being able to add "approved faces" to the dictionary. Kinda like with google doc spell check I can tell it a mis-spelled word is actually ok. So if my friend Bob is on the list and he's detected that doesn't count.
This is on the roadmap, along with gaze detection.

This model lets you upload a reference face and then matches to those in images. I think this allows for the "approved faces" function you mentioned.
I suppose a difficulty may arise when we run a few models at the same time, however there is probably a lot of room for efficiency on the table and thanks to the small model size we are already in a good place.
