Hi Atoms,
Yes!  Tuning the models isn't an exact science.  While the numbers are solid
against a single dataset or two (LWF and my library of 23k+ images and 18k+
faces), every library and machine is different.  The more feedback we get the
better we can deliver good software.

Download the latest build from https://files.kde.org/digikam/.  Steps to follow
for converting to the new models.
1. Start digiKam.  Make sure you download the new models when prompted.  They
are not packaged with the bundle.
2. Go to the people sidebar and change the settings at the bottom.  To start,
use these settings:
Detection Accuracy: 60% (7 starting in a day or two.  I'm updating the UI)
Model: YuNet
Face Size: Large
Recognition Accuracy: 60% (7 starting in a day or two.  I'm updating the UI)
Model: SFace

When you change from OpenFace to SFace for recognition you should get prompted
to retrain your database.  Click OK and let it run.  It may take several
minutes or more to complete.

3. Check if your computer is OpenCL capable by going to "Help->Components
Information->OpenCV Configuration->OpenCL availability" (optional, but will
make it faster)
4. If your computer is OpenCL capable, go to
Preferences/Configuration->Miscellaneous->System and make sure "Disable
hardware acceleration OpenCL" is unchecked. (optional, but will make it faster)
5. Run face recognition and detection and let us know the results!

Cheers,
Mike
