I can not reproduce the problem here. Which Windows version and which database type do you use?

Maik

Hi,

Sorry for my late reply. 

I use Windows 7 64 bits and SQLite database stored on C:\Users\me\Digikam_database\

Face suggestions disappairing

I take some screenshots :

1- Three suggestions are displayed
2- I correct and/or confirm (enter) the first then the selection goes to the second item. Suggestions are always displayed... :
3- Without interaction, after one second, suggestions disappairs and are replaced by "Who is it ?" text
4- I press "F5" to refresh and suggestions are back again

Thanks

nonobio,

The Windows installer have been recompiled with last changes from source code
and is available here for testing :

https://files.kde.org/digikam/

Take a care : it's a beta release. Make a database backup before to test.

Problem still here ?

Gilles Caulier

Thanks. I prefer wait for next stable release :)

Hi,

The issue is still here with Digikam 6.1.0.

I can not reproduce the problem with the last GIT version of digiKam-6.1.0. It is possible that the problem is resolved. Can you test it please.

Maik

Hi Maik,

Issue is still here with digiKam-6.1.0-git-20190328T184909-Win64.exe

Thanks

I can not reproduce the problem. Can you please post your metadata settings or a screenshot of it. Do you use sidecar, if so, also the exact settings.

Maik

Hi,

This is a screenshot of my metadata settings (i didn't capture all the "view" tab content; tell me if you need it) :

https://i.imgur.com/i7muiK5.png

I don't use sidecar for photos, just for videos.

Thanks

Hi,
The issue is still present with 6.3.0.
Thanks

Nothing has really changed between 5.x and 6.x about FaceManagement.

The big changes will come with next 7.0.0. I started to build pre-release bundles available at usual place:

https://files.kde.org/digikam/

Please test with this version.

Gilles Caulier

Is it risked ? I can wait for stable version...

Thanks

It's a beta. Create a new account and install DK 7.0.0 instead 6.x.

Import images in a new database and play with faces. Check if your problem still here.

After, uninstall 7.0.0, and go back to 6.x

Like this, using a separated account, you will not touch the production database generated with previous DK version.

Best

Gilles Caulier

By "new account", you mean : new windows user account ?
Maybe i could just try DK 7.0.0 on another computer...

This issue isn't urgent for me, i can wait. But if it can be useful for you to know if the bug is resolved in 7; i can test.

yes, one other account, or another computer, or.. a virtual machine, as you want...

7.0.0-beta1 is out with new Face Recognition algorithm based on Deep
Learning/Neural Network API from OpenCV

https://download.kde.org/unstable/digikam/

Please test and give us a feedback

Thanks in advance
Gilles Caulier

Hello,

I installed 7.0.0-beta1. I can't say if the issue is resolved because after analysing faces on a photo selection : none know faces are displayed. Maybe it is normal because it is a new Face Recognition algorithm ?

Thanks

digiKam 7.0.0 stable release is now published:

https://www.digikam.org/news/2020-07-19-7.0.0_release_announcement/

We need a fresh feedback on this file using this version.

Hi,

Sorry for my late reply.

I will test with Digikam 7.0.0 as soon as i can; i think in the next days or week.

Hello,

I tried with Digikam 7.1.0 win 64 but i have the same problem that with 7.0.0-beta1 :

I always have the "Who is it ?" field with none suggestions.

Also, if i compare to the 7.0.0 announcement post (https://www.digikam.org/news/2020-07-19-7.0.0_release_announcement/) : i can't found the same things like "reject this suggestion" button or the "help box".

Thanks

Please try digiKam-7.2.0-Beta1 whether the problem still exists. The training data must be rebuilt here as well. To do this, activate the option to rebuild the training data in the face detection/recognition section in the maintenance tool and run it.

Download from here: https://files.kde.org/digikam/

Maik

Hello,

After upgrading to 7.2.0-beta1 and rebuilding training data, a new analyze (doesn't ignore already analyzed) doesn't seem to give better results for me :

It doesn't found a lot of faces and i have none suggestions : all founded faces are "Who is it ?"

Thanks

After applying the recommandation of Maik in this comment (https://bugs.kde.org/show_bug.cgi?id=420128#c7), i had some suggestionsand i can now confirm that the issue is still here and exactly the same with 7.2.0-beta1.

Thanks

Hello :),

The issue is still here with 7.2.0-beta2.

A new detail : when i am in step 3 (see screenshot) : if i clic on "confirm", the name is displayed and saved.

Hi Nonobio and happy new year,

Please check with digiKam 7.5.0 pre-release windows installer available here :

https://files.kde.org/digikam/

Thanks in advance

Gilles Caulier

Hello Gilles,

Thanks and happy new year too :) .

I just tested with 7.5.0 and I have the same issue :( .

I recently investigated this issue. I couldn't reproduce it for a long time. To reproduce it, faces have to be so close together that the widgets overlap. Only then does the problem arise. So far I can say that deleting the name suggestions is not caused by the digiKam code. There must be an event within Qt, possibly related to the QComboBox/QLineEdit.

Maik

Hi Maik,

"To reproduce it, faces have to be so close together that the widgets overlap. Only then does the problem arise. "

Not for me : it happen even when widgets are distant and not overlapped, as you can see on my capture, and I just tried with 7.5.0.

I noticed something (since before 7.5.0), I don't know if it is important : when a suggestion is gone (but was present before to disappear) : if I just click on the "Confirm" button, the suggestion is displayed and confirmed (so I use it only if I had time to see that the suggestion was good). But if I just press "Enter" on my keyboard, to doesn't work.

Thanks

@nonobio

Hi,

I still have problems with version 8.5.0

Do you have any news?

Thanks :)

Hi,

We working first to integrate 2 new DNN models (YuNet + SFace) in the face management to improve performances of the detection and recognition. The recognition workflow will be changed/fixed for 8.5.0, but it's not yet complete...

Gilles Caulier

Thank you, good luck :)

Hi nonobio,
This definitely a UI issue, and not related to the detection and recognition engine.  I've experienced it, too. 

@Gilles and @Maik, I'll try to put together some easy and reliable steps to reproduce.

I can't reproduce it on different Windows/Linux installations. We select all the text in LineEdit when it gets the focus to make it easier to enter new text. Of course, any input is then enough to delete the text. Do you have any tools installed that might be related to the keyboard?

The program AutoHotkey sounds like a possible candidate.
Yes, please test the current version to confirm my theory or not.

Hi,

@nonobio,

Did you use only Windows or you can test also on a Linux computer using the 8.5.0 AppImage bundle or MacOS ? The idea is to check if the dysfunction only occurs under Windows or everywhere.

Best

Gilles Caulier

Hi,

I use Digikam exclusively on a Windows 10 PC.

I have a laptop with Zorin OS 17, I just installed digiKam-8.5.0-20241024T160054-Qt6-x86-64.appimage and I copied around ten albums from my main Windows PC.

To do the test, on an image with several faces, via the context menu, I start by deleting all the faces then I search for the faces, then I do "recognize the faces", but there, Digikam (Linux) does not do anything for me. suggestions, so I can't complete my test.

Is there a setting or an action to make so that Digikam makes suggestions to me like on my main Digikam?

Hi,

Under Linux,

- Did you download the DNN model files at startup ? If no, go to Setup/Miscs/System and press the button to process.
- The faces have been scanned before to recognize ?

Best

Gilles Caulier

Yes I downloaded the files during installation. I just checked in Misc/System/Download binaries: "All the files for the selected features have been found" (the 3 boxes are checked).

> The faces have been scanned before to recognize ?

Yes, at least I usually do these actions under Windows:
1- right click on an open image or on a selection from the list
2- look for faces
3- recognize faces

So I did the same thing there under Linuxand I have no suggestions

I managed to get the suggestions under Linux: I deleted the images from an album, searched for the faces, and I manually added the names of the faces of the first 10 photos, then I got some suggestions for the following photos.

In short, that was enough to do the test: the problem is not present with this installation of Digikam on Linux (Zorin OS 17).

I took the opportunity to compare the settings of the vertical "People" tab between my main Digikam (Windows) and this Digikam that I just installed for testing (Linux):

Processing Flow tab:

Skip images already scanned on Windows, Scan again and merge results on Linux
Detect Faces or Recognize Faces: Detect Faces on both

Configuration tab:

Configuration for face detection:
Accuracy: 7 on both
Model: Yolov3 on Windows, YuNet on Linux
Face Size: Grayed out on Windows, Large on Linux

Configuration for face detection:
Accuracy: 7 on both
Model: **OpenFace** Windows, SFace Linux

Work on all processor cores: yes on Windows, no on Linux

Could my settings in Windows be the cause of the problem, and in any case, are they correct?

I can said in first the settings of course :

>Face Size: Grayed out on Windows, Large on Linux

Good question. Why it's disabled under Windows, i don't know.

>Work on all processor cores: yes on Windows, no on Linux

Try only one core for both.

Gilles

There nothing specific in source code to disable the face size settings :

https://invent.kde.org/graphics/digikam/-/blob/master/core/utilities/facemanagement/widgets/facescanwidget.cpp?ref_type=heads#L269

Did you have the same git revision under Linux and under Windows (typically the same code compiled) ?
Look on Help/About digiKam dialog at "Git Revision" value.

Gilles Caulier

>>Face Size: Grayed out on Windows, Large on Linux

>Good question. Why it's disabled under Windows, i don't know.

I just tried to put Yolov3 in Digikam Linux, the image size also becomes grayed out.

>>Work on all processor cores: yes on Windows, no on Linux

>Try only one core for both.

I tried, the problem persists. Should I leave the setting like this anyway?

>Did you have the same git revision under Linux and under Windows (typically the same code compiled) ?
>Look on Help/About digiKam dialog at "Git Revision" value.

No:

Windows: https://invent.kde.org/graphics/digikam/-/commit/c663be55a32e00defc8eee5157f98ff63bb34f5c
Linux: https://invent.kde.org/graphics/digikam/-/commit/0ad1b22ca17502aba8a132da39916b9e0a4185a7

yes left the settings as well.

The git version sound like very near. I think it's not the problem.

I suspect a dispatch of signal broken or not properly done under Windows.
Another possibility is the thread management which looks different under windows and needs hacking. Even if one core is used, at least one thread run in background to process recognition.

Gilles

I haven't followed all the comments, but have you restarted your digiKam in Linux after downloading the models?

Maik

Ok Gilles, so there’s nothing we can do about it?

Hi Maik, I didn't restart Digikam Linux after downloading the binaries, but it's been done since. I only installed Digikam Linux to do the test: the problem of suggestions disappearing is not present.

I don't know if it can help but I just noticed something: when I have the problem (under Windows, therefore), clicking on the Show Face tags button twice, to hide then display again face tags, even quickly, allows you to redisplay suggestions. (like F5 which I have gotten into the habit of using).
I'm talking about this button:
https://i.imgur.com/n4K6LZh.png

Hi,

I just installed version digiKam-8.5.0-20241112T140208-Qt6-Win64.exe and the problem is still present.
https://invent.kde.org/graphics/digikam/commit/1ce745f7b2ccc648e74a7dd13b8b14c45993b39d

Is there anything I can do? I wasn't thinking, for example, of installing a portable version in parallel to test settings changes, but I am not sure if there is a portable Windows version of Digikam

Thanks

Hi,

I think I found the problem, at least what triggers it :)

I installed the same version of Digikam on another Windows PC (digiKam-8.5.0-20241112T140208-Qt6-Win64.exe https://invent.kde.org/graphics/digikam/commit/1ce745f7b2ccc648e74a7dd13b8b14c45993b39d) and the problem was not present 🤔

So I compared the settings one by one with my main Digikam 🧐 and I found that the problem is present (on both PCs) when the following setting is activated:
Show a count of items in Tree Views (Settings\Configure Digikam\Views\Tree-Views)
(On my test installation of Digikam, this setting is disabled by default).

So it is great :) I will be able to get around the problem when I organize my files, by deactivating this setting, even if it means reactivating it afterwards.
If you can make it so that this option can be activated without causing this problem that would be even better :)

I would like to take this opportunity to point out a small translation error in the interface (People\Settings):
Face Recognition Settings is translated into French in "Configuration pour la détection de visages", whereas it should be, unless I'm mistaken, "Configuration pour la reconnaissance de visages".

Hi,

We don't translated the application in French. It's delegate to the French KDE translators team. Please report at the right place :
