[digikam] [Bug 374180] New: Other tags assigned to the picture is disturbing when looking at face tags

            Bug ID: 374180
           Summary: Other tags assigned to the picture is disturbing when
                    looking at face tags
           Product: digikam
           Version: unspecified
          Platform: Other
                OS: Linux
            Status: UNCONFIRMED
          Severity: wishlist
          Priority: NOR
         Component: Faces-Management
          Assignee: [hidden email]
          Reporter: [hidden email]
  Target Milestone: ---

Confusing when wrong name appears under face tag.

When I choose People and select (a) name(s) for which I have face tagged my
photos, only the marked areas of the pictures with the chosen name(s) appear.

Under the face tag all the tags applied to the pictures appear. This is
confusing. It seems more natural that only the tag for the marked part of the
picture appears, or at least that the tag for the marked part of the picture
appears first.

*************************************

Face recognition.

Is it possible to deselect marked faces from the face recognition function.

Face tags are used to find picture with defined people, but some of the
pictures are in such a state that they will only confuse the face regognition
algorithms. Is it possible to mark these somehow to reduce probability of
confusion ?


**************************************

Tags applied to faces could be separated from tags applied to picture when
looking at the picture.


When we are looking at a picture it could also be nice to separate between tags
applied to marked faces and tags applied to the whole picture. I would like
this because I have some pictures to which I applied tags with names of people
without marking the faces. I would like to delete these tags.

Can you test, just to verify, if the problem still exist with Linux universal
AppImage Bundle available here :

I still see all the tags applied to the whole picture when I select people tags
and one of my names which I have tagged.

So under the part of the picture with Gilles Caulier , Andreas would be shown
as the first tag if Andreas also was on the picture and face tagged as Andreas
is before Gilles in the alphabet.

I am not sure I understand exactly how to reproduce this. Is it the
following:
Select a picture with multiple already tagged faces on it. Look at it in
"Preview" mode with "Show Face Tags" activated. Then you see all names
of people on the picture below every face tag area?
If this is the case, I can't reproduce this issue. I only see the one
name assigned to the specific face area.

Created attachment 103154
  --> https://bugs.kde.org/attachment.cgi?id=103154&action=edit
Shows my selection and the confusing extra tags.

Hi Simon.


I am sorry for the somewhat unclear description of the problem.
Trying again.

See picture.
I have selected people tags, Odd Harry, and thumbnail view, ( not preview and
show face tags )
The thumbnails shows only the marked part of the pictures with my face on, but
below the thumbnail all tags for the whole picture is listed.
Also other peoples names if they are tagged on the same picture.

I hope this helps reproducing the slightly confusing situation.

Thanks for the screenshot, it definitely helped me understand.
This is however not a bug but intended. The information displayed below
the thumbnail in icon view is specific to the entire image also with
active people sidebar. Only the overlay that allows to confirm/type the
name or discard the face rectangle are specific to the view shown with
people sidebar active.

Regarding your other two questions:
 - There is no way to mark a face but not use this face for face
recognition.
 - There is also no way to separate tags applied to the entire image and
only to areas. Every tag applied to an area (i.e. face) is also applied
as a tag to the entire image.

Hi Simon

I agree that this is not quite a bug. I believed I had classified it as a wish,
not a bug, but I may have failed.
It is good that the picture helped you understand.
Here is a further explaination on why I found it confusing.
When I add names to the automatically selected rectangles with detected faces
after running face detection I simly chose the people tag, and then I worked in
the thumbnail view. If a picture had a face which I already had given a name
this name would appear below the thumbnail of someone elses face.
It is not a big problem, but it is confusing.
Especially as I ended up in the thumnail mode without choosing this actively.

It is more confusing when I have only chosen the people tag, than when I
already have chosen one particular name to look at.

In the "preview image" mode it works perfectly when I let it "Show Face Tags".

So again, I agree that this is not a bug, but I am still of the opinion that
the interface could be further improved when the people tags is chosen and we
are in the thumbnail mode. It is a thumbnail of the marked face which is shown,
not a thumbnail of the picture.
