https://bugs.kde.org/show_bug.cgi?id=423113 --- Comment #12 from Michael Miller --- Yes, as Maik says, you need to rebuild the training database using the maintenance tool. I'm planning to fix this issue when I rewrite the entire facial recognition system after then 8.5.0 release. -- You are receiving this mail because: You are watching all bug changes.

A rebuild of the training database with the maintenance tool is still necessary. Maik -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=423113 --- Comment #9 from caulier.gil...@gmail.com --- Hi Nghia, No conflict at all. All compile fine. I currently review all code step by step... In the digikam-de...@kde.org, an user has already tested the new code (just after i merge the branches this morning) and has a question for you. Look here : http://digikam.1695700.n4.nabble.com/Digikam-7-2-faces-updates-td4713606.html Gilles -- You are receiving this mail because: You are watching all bug changes.

Therefore in order to delete the face embedding in the database, we have to add an additional association between face item and face embedding. If I do it now, it will add up more conflicts to our projects. Therefore I will find a way to do it after the 2 projects merged.

https://bugs.kde.org/show_bug.cgi?id=423113 --- Comment #5 from Kartik --- Hi Nghia, The Top Level Connections for the Deleting button are done in DigikamItemView. The Delete Button forms part of a FaceRejectionOverlay, and the signal for pressing the delete button is set here: https://invent.kde.org/graphics/digikam/-/blob/master/core/app/items/views/digikamitemview.cpp#L342. The removeFaces(https://invent.kde.org/graphics/digikam/-/blob/master/core/app/items/views/digikamitemview.cpp#L411) method then delegates deletion to a FacePipeline. I think you might be familiar with FacePipeline functionality. DatabaseWriter works with the FacePipeline and picks up the package (when its time for being processed arrives), and then calls the FaceUtils method for actual removal of the Image-Tag association: See this connection for DatabaseWriter with FaceUtils: https://invent.kde.org/graphics/digikam/-/blob/master/core/utilities/facemanagement/workers/databasewriter.cpp#L142. There's multithreaded implementations that lead to DatabaseWriter picking up the package sent via FacePipeline, however it isn't necessary to worry about that in my opinion.

Maybe we can add a reference counter to delete the registered identity as well when there isn't any face left? Could you point me to the code of the deleting button so that I can have a better understanding of the workflow here? Nghia -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=423113 --- Comment #3 from Kartik --- Hi Maik, rebuilding the training database is certainly a good idea to avoid this error. I wasn't aware that feature existed. It's certainly desirable for Faces to remain in the database, if an Image is deleted. However, if the User presses (x) on a Face, then he does want to Delete that face (not delete the Image). If the user is implying that this is not a face, then why is it being used as Training Data? Apologies for any inconvenience.

https://bugs.kde.org/show_bug.cgi?id=423113 Maik Qualmann changed: What|Removed |Added CC||metzping...@gmail.com --- Comment #2 from Maik Qualmann --- Yes, the behavior is as described. In principle, it is even desirable. It is only problematic when a face is changed, but there is an option in the maintenance tool to rebuild the training database based on the currently confirmed faces. This should be done from time to time to ensure good recognition. The incorrect identity is then removed. Normally, a face should not be forgotten when you delete an image, for example. The face should be found again later, so there is no deletion in the face database. Maik -- You are receiving this mail because: You are watching all bug changes.
