Version: 2.0.0 (using KDE 4.5.5)
The People tags can be used in two ways:
(1) manual tagging of photos in the same way that any other
(non-People) tags are used
(2) tagging by the face detection/recognition code
Clearly the backend makes a distinction between these uses - I think
I'm right in saying that basically (1) is governed by the ImageTags
table, whereas (2) is governed by the TagProperties and
ImageTagProperties tables which use person/kfaceId and
tagRegion/autodetectedFace properties respectively.
However, the way this is presented in the UI is confusing. The Tags
sidebar corresponds to (1), but when you use the People sidebar you
get a mix of (1) and (2): the image counts shown in parentheses
correspond to the number of photos with that manual tag as per (1),
but if you click on that tag, the preview pane in the middle only
shows photos matching that tag as per (2).
So for example if you manually tag 50 photos with 'People/Joe' before
you do any face recognition, and then via face recognition tag a
further 10, you will see 'Joe (50)' in the People sidebar, and if you
click on it, you will only see 10 photos in the middle pane. This is
difficult for a normal user to understand.
I'm not sure what the best UI solution for this is, but ideally it
should allow some way of showing any of the following:
- all photos which have a tagRegion corresponding to Joe
- all photos which have a tagid corresponding to Joe but no
tagRegion - this could be useful for example prior to exporting to
facebook to ensure that any photos containing Joe would be
properly tagged in facebook (which requires a tag region)
- all photos which have a tagRegion corresponding to Joe but no
normal tagid (although it looks like digikam automatically adds a
tagid when setting a kfaceId/tagRegion? in which case this case is
Do we have any UI design experts who could help?
See also bug 265025 for other face tagging usability issues.
Can we agree there is a bug that the counter in the People sidebar is showing the wrong number?
It's quite simple - there is special handling missing/unimplemented for this case, so you just get the default behavior. It's no design decision ;-)

OK :) So fixing the counter would be great. But it would also be extremely useful to implement the second use case I listed - "all photos which have a tagid corresponding to Joe but no tagRegion". (The first use case is the current behaviour, and the third one is probably not needed.)
Does export to facebook include the tagRegion already? If not, I will file an enhancement bug for that ;-) Thanks!
Ok, the counter is fixed by now (in some other bug report).
Remains the wish to list tags with no tag region assigned. It's not really
difficult in the backend, but I dont know where to put this into the UI.
