Hi HubMiner,
The face engine is comprised of 3 main parts: face detection, feature
extraction, and classification (matching). If you are seeing the face in the
People->Unknown view, then the first step was successful.
digiKam may not match a face for 2 reasons. The first reason is the AI can't
extract the features, which means it can see that it is a face, but it can't
get the details it needs to create a "thumbprint" of the face. The second
reason is that digiKam can't or won't match the "thumbprint" to other faces.
You can easily test the second scenario by setting the recognition accuracy
slider to something low, like 2 or 3, and then doing a recognition scan. Don't
worry, this won't mess up your library. You can put it back to exactly where
it is by setting the accuracy slider back to it's present value and then doing
another recognition scan.
Try that and see if the face get's matched to anyone.
Cheers,
Mike
