Bug ID: 502052
Summary: Not detecting rotated (on an angle) face
Classification: Applications
Product: digikam
Version: 8.6.0
Platform: Microsoft Windows
OS: Microsoft Windows
Status: REPORTED
Severity: minor
Priority: NOR
Component: Faces-Detection
Assignee: digikam-bugs-n...@kde.org
Reporter: craigfryer...@gmail.com
Target Milestone: ---
SUMMARY
Not detecting a face rotated about 60 degrees for the frame of the picture.
The face detection has improved greatly over version 8.5 & 8.6. Thank you.
STEPS TO REPRODUCE
1. I had a series of photograph where there were two faces appearing with one
roughly aligned as normal and the other rotated about 60 degrees from the
other. The normally aligned face had no problem being detected. However the
rotated on was not detected. I had face detection set to medium size and
Accuracy set to 7.
2. I then progressively lowered the Accuracy to 5, then 3 then 1. In none of
these cases was the rotated face recognised.
3. I then increased the face size to Large, but the rotated face was still not
recognised.
4. I then cropped the image to include only the rotated face, but rotated. The
face was not recognised. Size Medium. Accuracy: 7.
5. I then rotated the face to be aligned normally and the face was recognised
as expected.
EXPECTED RESULT
I have seen many times before where Digikam has recognised rotated faces, so I
just thought this was unusual and should be brought to your attention.
Unfortunately the image contains people that don't want their image shared
publicly. I could probably share the image with just a developer directly.
SOFTWARE/OS VERSIONS
Windows: 10
ADDITIONAL INFORMATION
This isn't a critical problem and it may be solved through future updates.
