Description Marcos Dione 2023-06-22 12:50:31 UTC

The face detection algorithm is very good, to the point where it detects faces out of focus, in really bad angles, etc.

While using the People view to tag faces, we can tag these 'bad' faces. It would be nice if we could tell digikam not to use them for training the face recognition tool. I have the impression that when doing so, the algo starts confusing all the out of 'bad' faces, so the algo's hit rate plummets.

Maybe related to https://bugs.kde.org/show_bug.cgi?id=425263

Other reasons for 'bad' photos:

* Partially occluded
* Bad lightning
