adding face-are without adding person-name as tag

[EGore]

Hello everybody,

I'm new to this list and of course I'm a new dK (5.6) user as well.

I use dK mostly for organizing my photos more than to edit them. The
last years I used picasa for this, espacilly because of the face
recognition.

I now tried to use face recognition in DK and it seems to work quite
well. But there is one little detail which is annoying me.
In Picasa the face tags (x, y, width, height and person-name) were
written into the Metadata of the file (because I said that picasa has to
add it into file and not into database). I also used tags for organizing
the photos like outside, birthday, party, ...
When I now add a face tag in DK there is Metadata added to the database
and of course to the file (because I activated it in Settings->Configure
digiKam->Metadata->Behaviour).
But additionaly to the Metadata itself the person-name is added to the
"normal image tags". You can see this in the column "tag" in windows
explorer for example. So there is not only "outside, garden, birthday"
the tag is now "outside, garden, birthday, peter, paul, ...".

I tried to change the settings in Settings->Configure
digiKam->Metadata->Behaviour and turned "Image tags" of. But then really
no Image tag is written to file (no "outside, garden, birthday").
I then tried to turn "Face tags (including face areas)" of. I'm not sure
if the face tag (x, y, width, height and person-name) is still written
to file but the person-name is still written to the "normal image tags".

Does anybody have an idea, how to change this behaviour?

Thanks in effort.

Sebastian

In digikam's database, indeed the assignment of the tag "Peter" is
prerequisite to storing a face region for Peter at all. It's more like
assigning the tag is the fundamental action, and the region is metadata for
this particular image-tag assignment.

If I understand you correctly your problem is that the tag is written to the
normal tags and you would like not to write person tags into the normal tag
metadata? I dont think it's implemented.

Hi Marcel,

thanks for your post.

Yes, you're right. I don't want the person to be included in the "normal
tag", because this leads to very "crowded" tags.

The imported and already tagged photos from picasa don't show the
persons in the normal tag. Altough when I open these old photos in dK,
the tags and the faces are displayed correctly.
He shows all the tags and he shows the face-rectangles correctly.

Depending from where you check the tags, only the image tags or the
image tags including persons are shown (for the old photos).
In thumbnail-view the tags including person are shown.
In properties->digiKam Properties or in Metadata->Keywords only the
"normal tags" are shown.

If I add new face-rectangles with dK the additional person tag is added
to the "normal tags". Then I altough see them in properties->digiKam
Properties or in Metadata->Keywords.
Therefore it seems that dK can handle this kind of saved face-data
correctly, but is not able to save it in the way it was done before/I
would prefer. :-/

Best regards
Sebastian

Hi,

I searched a way to change this behaviour in dK again.

I tumbled again over Metadata->Advanced.
I assume that, if it possible at all, this could be the right place to
change is.
Maybee it is possible to change the entries in tags->write options for that.
But I don't know how to implement something like a filter here.

Even if it's not possible to change the behaviour the way I want to...
could it be possible to deactivate the whole tag-metadata temporarly
when adding new face-rectangles or use the face-recognition feature and
enable it when doing the "normal tagging job" to reach my target?
Cumbersome but better than nothing I think. ;-)

Thanks so far.

Best regards
Sebastian
