Face Recognition in DK 8.5 - are ignored faces learned?

[Michael Miller]

Hi Steve,
Your suspicions are correct. Ignoring a face does nothing to face training. We don't save the ignored face data for any type of matching or training.

We thought of, and I experimented with matching ignored faces to make it easier to ignore similar faces. Ultimately, we rejected it because a false positive match to an ignored face could cause you to miss an otherwise important match to a real person.

Cheers,
Mike

Subject: Face Recognition in DK 8.5 - are ignored faces learned?

Hi,

I'm using the new default recognition settings: Accuracy = 7, Model = SFace.
And I'm very pleased with the results.

I have a question about the "Ignored" tag.  I've chosen to tag only family and
close friends.  So when there is a gathering of another kind, I may find 10
other people in the background of 20+ images.

My question is: if I tag one image to ignore all those people, will a
subsequent run of face recognition find a match, and see that it is ignored,
and then go ahead and mark that face as ignored?

My experience is that the answer is "no, that's not how it works".  I
generally have to ignore all those background people in all the individual
images.  If that's accurate, then: is the described alternate behaviour
feasible and useful?

Thanks,
-Steve
