Description MarcP 2018-03-18 20:46:09 UTC
This is not a big deal, but could improve usability.

When detecting and recognizing faces, Digikam could group faces by similarity in the "Unknown" person when it's very certain that they belong to the same person, even if that person's name is not in the database yet. That way, only writing the name of one of them would face-tag the whole group. Just an idea, I am not sure if it's even possible with the current face recognition engine.

7.0.0-beta1 is out with new Face Recognition algorithm based on Deep
Learning/Neural Network API from OpenCV

Please test and give us a feedback

Thanks in advance

Testing at this very moment :)

One thing about face recognition, is that new users wouldn't know what to do to start recognizing new faces. Basically you first have to detect the faces (can be done from the right-click menu too), then manually tag at least 4 or 5 faces for each person, and then run the face recognition algorithm. Maybe a little message with these instructions could be displayed to the user the first time they opened the recognition panel? (Like the one you get for the similarity search).

I am also trying to see how it works with an existing face database. Since so far I had only tried it with controlled face datasets.
