[digiKam-users] ghost faces marking

[KRODER Gerhard]

Hei,

additionally faces markings seem to be gone now, by proper setting and 
re-read metadata with clean up, but lots of verified markings still are 
heavily misalinged (only partially, or not at all on face).  Is there a 
more "easy" way to restore faces alignment, other then deleting all, or 
manually checking/fixing each single image?

Looking at faces previews gives a rough estimation of about 15-20% of 
all  faces having been verified before, belonging to about 1700 images 
(and affectin other faces on this images, too)

Cheers,
Gerhard
