[digiKam-users] Image recognition

[Hubert Zillner]

Hi Maik and others,
thank you for the suggestion. 
I have run the rebuild of the training data ( tools/maintenance/detect and
recognize faces [Clear an rebuild all training data]) which took a lot of
time (13,5 hours). 
After this task I see in the people tag "unknown" many many faces and if I
click to one face the preset of the field is "Who is this?" and I can assign
the name manually out of the people list. When I click another face the name
of the previous face is preset. 
My expectation is however, that after a recognition run all the recognized
faces are in the people tag "unconfirmed" but there is nothing at all  in
this tag. 
Also my expectation is, that I can choose a folder within an album (right
mouse) and activate "scan for faces" to get all recognized faces in
"unconfirmed" which I only have to confirm afterwards manually. 
So the question is, do I apply this function wrongly, or rather what should
be the result of the whole process?
By the way my operating system is Windows 10. 
Regards
Hubert

It is important that you rebuild the training database with digiKam-7.2.0.
To do this, select the checkbox for rebuilding the training data in the face
detection/recognition section of the maintenance tool. A special album
selection is not necessary, all currently confirmed faces are used. The face
recognition works best with face rectangles, which were also detected by
digiKam. Face rectangles from other programs, e.g. Picasa or manually drawn
face rectangles, work poorly. The current face recognition can deliver over
90% correct results.
