The problem is finding the mis-tagged face.
I have collections in which a few persons occur hundreds or thousands of
times. It is almost impossible to find a face that is mistagged in a
haystack of thousands of faces that look similar enough that the user
Worse, now the app will be trained that this incorrect face belongs to
this person (which it does not) and then it will learn to recognize it
as such causing the face recognition quality to decline rapidly.
I wish there was a way to sort images inside a "person album" after when
they were tagged so that you could easily identify the mistagged one.
And also: A way to sort by how confident the algorithm is on the match.
I think it would be possible to have the algorithm work for the user
here: if it assigns a score of how well a face matches a given person
(and I guess it does, because you can adjust this threshold) then
sorting by that score would make it easy to find the ones that look the
least like the person they are tagged as.
Now, when you have identified the mistagged face, then you have a
different problem: how to properly undo this tagging. This is rather
confusing. I don't see a Right click --> This person is mistagged, undo
face tag for this person. But I think I have already started a thread
about that issue a while back...
