            Bug ID: 447767
           Summary: Face detection on Sony ARW files does not detect the
                    correct face area
           Product: digikam
           Version: 7.4.0

Face detection screenshot

SUMMARY
When using Sony ARW files from a Sony Alpha 6000 mixed with JPG files of
various sources and using face detection the JPG files show the expected
outline after detection but ARW files show an elongated rectangle including the
neck and sometimes chest but missing part of the face. This also seems to
poison face recognition training resluts (unconfirmed) but shows a seemingly
valid face area in the recognition confirmation tool window.

STEPS TO REPRODUCE
1. Import JPG and ARW files from multiple Folders
2. Select YOLO v3 and 90% recognition
3. Open any ARW file with faces
4. Right click -> select detect faces

OBSERVED RESULT
Rectangles do not fit faces. https://imgur.com/a/KK1QfRB

EXPECTED RESULT
Rectangles should fit faces like for JPEG

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: not using plasma (XFCE 4.16)
