YOLO is only for face detection, you only need YOLO if you want to recognize
very small faces, blurry faces or group photos with many faces. YOLO is much
slower.
I can only guess where the 21 unknown faces come from, they must be in the
metadata, in digiKam < 8.0.0-Beta1 it could happen that unknown faces were
written in the metadata.
First they have to run face detection, they should then have a statistical
number of unknown faces depending on the collection. Now enter a name for the
unknown persons, there should be at least 5 per person. Now let face
recognition run. Now they should have many unconfirmed faces, if correct - then
confirm otherwise reject.
Run face recognition again, name other unknown people, etc...
Simply put, the training database is a mapping from face fingerprint to a name.
Therefore, it can always be built up from the already confirmed faces. The
rebuild should have done whenever they misconfirmed a lot of faces, changed a
lot of names, etc.
Another note: Face recognition currently only works well with faces that have
been automatically detected by digiKam. Not with manually drawn face rectangles
or faces from other programs, e.g. Picasa.
