Comment 3 Maik Qualmann 2021-11-26 11:28:28 UTC 
With a similarity setting of 95% -100%, digiKam recognizes both images as identical without any problems. My guess is that you haven't updated the fingerprints, you have to do this every time new images are added or created.

Hi,

Same s Maik here. I tried different similarity settings under Linux and images are detected with threshold over 95%.

Best

Any feedback here? Fingerprints updated?

No feedback, it works for Gilles and me, I'll close the bug.
Note: In the meantime, the recognition of the reference image has been improved.
