Facial recognition creates duplicate regions

Triffnix

I have installed Tonfotos successively on multiple Windows and Linux PCs, with and without CUDA. The image library is located in a network folder on a file server. All scan and storage options for this library are turned on in Tonfotos.

After installation and configuration, Tonfotos always begins an hour-long scan of the library and imports previously detected faces. It also detects faces that have not yet been marked, as expected. However, many of the “new” faces are faces that have already been marked. After each installation, additional duplicates are added. I have seen up to three duplicate entries for the same face.

This behaviour makes sharing a library rather inconvenient.

Triffnix How long ago did you install first version of the Tonfotos? At some point in time we made minor adjustements to face recognition algorithms that probably resulted in slight changes in face coordinates, but changes supposed to be minor, not something affecting you on the large scale.

How many of the files are affected by this issue?

Andrey The first installation of Tonfotos was the free version of 1.9.5. I did some tests and stopped using it. A few days ago I installed 1.13.7 (Windows) and 1.11.4 (Linux) with a full license and started tagging faces in earnest. This is when the issue appeared. I have not checked the entire library, but it feels like a one digit percentage of all files with people is affected.

About half of the duplicates have differently sized regions, but the other half seem to occupy the exact same regions - at least visually. The duplicates are either marked as “unknown” faces or as a suggestion for a different person.

Triffnix Thank you, I see. If that would be just few images, then soluition would be to delete all faces from the image, then re-index it (that would re-dectect faces again), and then there would be no duplicates and you would be able to assign faces to people.

However, if that is singe digit percentage, this manual approach is not the best option, I guess. Is there possibility to send me few images like that together with corresponding .tonfotos.ini files? I would then debug it myself and try to find general solution (fix a bug if there is a bug).
