[digiKam-users] face detection with 7.2RC 1st try

[Maik Qualmann]

Face recognition is carried out on all images with "Unknown" faces. So all 
faces under the virtual tag "Unknown" in the People view. Album bassierd 
wouldn't make sense. You probably don't even know which albums the unknown 
faces come from in order to choose the right albums.
The training database rebuild is not album based either. All known faces are 
used.
