Bug 336253

Why not to use Color Labels for this task. With 4.2.0, it's now possible to show all items with a specific label assigned.

Sorry, did not understand, how would i use this to find out with images are not confirmed yet?

Example : Select all unconfirmed faces after a detection process and assign Red color label. In Labels view you can find quickly this set of images. When face are assigned to one Red labeled image, remove Red from it.

I could also do this with a simple tag. I will do something like this.. i might just add a new tag to all my images, once i confirm a face a will have to untag it.

It does not seen pretty, but does the job.

I still think it could be shown somehow, as this information is already saved somewhere.

I second this feature request: It is very unwieldy to manually filter all images with unconfirmed faces.
When I select people and then a person I see pictures but can't select which ones need to be confirmed. Even if I had tagged them before "unconfirmed" there would be no way to know if the picture had other - potentially unconfirmed - faces on but to start preview mode.
It would be great if these steps could be avoided by having digikam keeping track of unconfirmed faces in a way easily selectable / filterable.

I also second this feature. CUrrently, I need to move the cursor over each one of the 1500 photos of my wife to see which ones of them are "new"

I also second this request.

It is unpractical for me to introduce a manual color selection, as when I want to check the unconfirmed for my wife I only want to see these, and not all unconfirmed for every other person.

I'd even work on this myself, but so far I'm lacking the insight in the digikam source. Any developers close to Baden, Switzerland?

Gives the option to inverse the normal filtering

Hi all,

I created a solution for myself which works quite well so far. I changed the normal filtering in a way, so that the selected tag is filtered out, instead of filtered for.
So I open the faceview which shows all confirmed and unconfirmed pictures of my wife, then I select her name in the tag filter on the right and all the confirmed pictures are filtered out and only the unconfirmed are left.

The inversion is done via a checkbox, so the normal way of filtering is not lost.

Let me know what you think.

BR,
Chris

Yes, perfect!

The inversed tags filter mode is already included in digiKam. Right-click on the tag in the filter->Tag Filter Mode-> Must Not Have This Tag

Maik

Thanks Maik. Should have read the manual, I guess.

WIth the option explained by Maik, for me any other feature is not needed.

Note: The inversed selection of tags is also possible with the middle mouse button.

Same here, the existing feature addresses my needs perfectly.

So, file can be closed as well ?

Gilles Caulier

This does not work if you manually tag person before.

Or i missed something?

And the this only works if you want to confirm a specif person..

If you just want to confirm or not all pictures that are unconfirmed that is not possible...

After trying this out for a while, I agree with the last comment. I have a large number of people tagged, and having to check them one at a time for new unconfirmed matches is very tedious. It would be much better if all unconfirmed faces could be shown in a single list, grouped by person.

Yes, I would appreciate such a feature as well. I knew it from Picasa a long time ago, that was great...

Just a note in regard to the workflow of comment 13: For me it (quite immediately) ended with digikam 3.5 in bug 338176 (see also bug 323888 as you may have to relearn faces to resolve bug 338176).

I wholeheartedly agree to comment 19.

Just using the newest DigiKam 5.0.0 now, and this is still an issue. 
I have many faces detected in my thousands of photos. 

The method of finding photos without a tag does not work, as the photo gets a tag when there is another already tagged face in it. 

Really, we need a tag called unconfirmed face, and grouped by who the software thinks it is.

I'm willing to work on this issue given minimal direction from core developers.

Patch for unconfirmed Person tag

I second the feature request, too.

But I think using filters is not so nice. The user would have to mark the faces before recognition. And he would have to mark all images he imports.
Meaning: When we have a Unknown tag, why don't we also have an Unconfirmed tag where all unconfirmed images are shown? The user could see transparently
which faces need to be confirmed and does not need to add markings which he has to remove at the end again.

I took some time at the weekend to find some way to accomplish that.
In fact it was not even this complex.

I introduced the new special tag Unconfirmed which is automatically created if not present. In detection phase, faces are marked as unknown as usual.
In recognition phase, the faces are marked with the recognised face tag, as usual. But additionally, they are connected as autodetected person to the Unconfirmed tag. In this property, I store the id of the person as which the face was recognised and also the face region. 

With small adoptions in the image lister all recognised faces are now shown both in the face tag which was recognised (person A) and the Unconfirmed tag (with the suggested tag being person A).

Confirming the person can now be done in both tags. And the confirmed identity is set as expected. Confirming the face also removes the face from unconfirmed tag.
Rejecting the face also removes the face from both the recognised tag and also from the Unconfirmed tag. Rescanning for faces (detection) also removes the connection
to the Unconfirmed tag if unconfirmed results should be thrown away.

Can someone revise my patch?

I don't have time to look at it in the moment, but one question: Would
it also be (easily) possible to show unconfirmed faces of just one
person? Maybe a switch to show unconfirmed only, confirmed only or both
instead of one "container" with all the unconfirmed results.

I currently see no easy way. The only thing that *could* be quite easy
is grouping by face tag.

I take a look in patch, and it's sound fine. I don't yet tested it. I will do it this evening.

Gilles

Mario,

The patch work as expected here. perfect.

Wolfgang, 

As the workflow have changed for face recognition step, this must be described in handbook.

Mario,

Turn on "Setup/Views/Tree-Views/Show a count of items..." option. Unconfirmed tag still at zero.

Committed on 16/01/2017 at 20:20.
Pushed by mfrank into branch 'master'.

This patch introduces the functionality to filter tags for assigning.
Only face tags are given if configured so. The setup option is located in misc setup settings.

Also, the Unconfirmed face tag now shows the count of contained faces.

Hey Gilles,
fixed that one, too.

Will see what I can fix in the next days. For today I'm done ... headache.

Thank you guys.

I'vent really used face detection because of this.

Actually i need to update my digikam installation.
