Choosing a caption using the drop down box in the full image view
The face detection and management is a big step forward and I like it.
I like to give some feedback about my experiences with the hope that an
improvement is also useful for many other digikam users.
Using the face detection, digikam has some problems making face management very
hard.
The issues are related to the label / caption hierarchy. For correctness to my
setup, I am using german but I guess this should not really matter. Here a
snippet of the hierarchy I have setup:
Stichwörter (the root)
|-- Lebewesen
| |-- Personen und Haustiere
| |-- Familie
| | |-- Anne
| | |-- Reiner
| |
| |-- Freunde
| | |-- Mueller
| | | |-- Maria
| | | |-- Michel
...
|-- Personen // created by Digikam as default place for face recognition
Before face detection was available I had already manually labelled many images
with face tags. Of cource face tags means that I have had created a label
(caption) subtree, see "Personen und Haustiere".
For the face detection another subtree below "Personen" is automatically
introduced which caused problems.
Problems:
1) When running face detection on an image which was previously labelled at
whole, the caption cannot be choosen to be re-assigned particulary fro whe
image to the face. Moreover it is not possible to choose it (maybe because it
is already assigned to the image?). I think that should be possible because
this caption is related to the person no matter where it is attached to the
image or to the designated face in the same image. And the face detection
mechanism cannot be configured to ignore this album forever (which would be a
work-around only).
2) It is not possible that I can manually configure my subtree in the captions
named "Personen und Haustiere" to be used for the face detection.
Moving to the automatic created "Personen" top-level subtree is not my wish
because of using another system and it would place much work to me.
3) Due to the difference between the preset top-level tree of captions, some
captions below "Personen und Lebewesen" and some below "Personen" are used.
I. e. creating new captions during the management will be placed below
"Personen" while choosing old ones use those below "Personen und Lebewesen".
This leads to a mess. For me all, new and old, captions should be below
"Personen und Lebewesen".
4) After the face recognition was done and I do the assignment using a known
caption with the drop-down combo box as supported in the full image view. As
the hierarchy of captions is huge by high number of captions and deep hierarchy
the displayed combo box is too small - even I am working using a 4k display,
which provides much more space. Please have a look to the attached screenshoot.
5) Using the dialog to run the face detection only within a subset of all
albums, will display a combo box for the albums. But it is not possible to
reset the previous made selection with a single action. Instead I have manually
to run through the whole hierarchie of almbums and try to find which one was
selected in the previous run.
A suggestion would be to have a list of all albums on the left side and the
choosen albums are displayed on the right side. For example, this concept is
used for example when configuring the buttons in a KDE menu bar.
6) Any face detected need to be assigned to a caption. But what is the best way
to remember that a face is to be ignored? For example my family and me did
visit a historic metal mine on holidays. My family was part of a larger visitor
group. Thus on some images there were quite more faces detected than I am
familar with and for which I like to provide captions.
7) Regression error: with the current release (5.9.0) the face detection does
not correctly work on the choosen album. Instead quite more albums will be
used. Of course the check mark "Gesamte Almbumsammlung" (All Albums) has been
not checked. In my previous digikam release (5.6.0) this was working as
expected.
Best regards,
Reiner
