Description Petr Schonmann 2022-10-12 19:00:05 UTC
STEPS TO REPRODUCE
1. Take a large image collection with faces already tagged.
2. Start face detection and recognition.
3. Look into suggestions.

OBSERVED RESULT
Overlapping rectangles show a name and digiKam suggests a different name or nothing for the recently detected face.

EXPECTED RESULT
Rectangles are merged or at least the existing name of the overlapping face is used.

We're checking a certain percentage of overlap. We can change it, but then there is the problem that faces that are close together are ignored. I would almost leave it as it is at the moment, the problem occurs very rarely. Please provide me with the original tagged image.

Comment 4 Maik Qualmann 2022-10-13 06:31:34 UTC
This type of double faces can only occur when re-reading the metadata from the image. Function is now improved for digiKam-8.0.0.
