Face Recognition

[Charlie Gorichanaz]

Hi Mick,

If you do not have a huge number of faces tagged and really want to just
start over to get your process figured you, you could make use of the very
scary *Reset and clear all faces and training *option in the Tools >
Maintenance menu described in the manual on the bottom of the page Detect
<https://docs.digikam.org/en/maintenance_tools/maintenance_faces.html> and
Recognize Faces
<https://docs.digikam.org/en/maintenance_tools/maintenance_faces.html>.

Otherwise you can select files in several different views, right click and
select Remove All Faces. I believe that should allow a subsequent Scan for
Faces operation to act like you had just imported those photos and not done
any face tagging yet. You could do this from the root album with the View >
Include Album Sub-Tree option selected, or you could go to your People
sidebar and select many photos that definitely have faces tagged already,
and then right click as described.

Regarding your earlier question about confirming all suggestions for a
person: What I do is click the horizontal bar with the person's name, which
seems to select all photos contained under it. I then scroll down to
confirm they are actually correct, and hold down Ctrl + click any to remove
from the selection. Then when I get to the bottom for that selection, I
hover over any of the selected photos and click the confirm/checkmark
button. That seems to apply the confirmation then to all selected photos.
Note I occasionally have issues with this if I somehow triggered a rescan
in the background, which is possible with some of the settings.
