Bug ID: 432764
Summary: Face detection (!) with few results
Product: digikam
Version: 7.2.0
Platform: Other
OS: Other
Status: REPORTED
Severity: normal
Priority: NOR
Component: Faces-Detection
Assignee: digikam-bugs-n...@kde.org

Target Milestone: ---
Hi,
I'm using face detection and recognition. With 7.2.0-rc the recognition
improved a lot, thanks for this handy functionality! I was told the algorithm
works better, if I don't mark the faces manually. So I'd like to work with face
detection, but I would have expected much more faces being detected by the
functionality.
Scenario: I tested with a album/folder of about 25 group fotos (typical school
and club fotos, 20-50 people per foto) and 10 other fotos with 1-5 people. Face
detection results in only 10 detected faces, not a single one from the group
fotos. Also tried to lower accuracy parameter with the hope that it also aplies
to detection, but with no improvement.
Is there a minimum size for faces on fotos to be detected? (If I had to
estimate such a parameter, I'd say faces needed to cover more than 1/10 of
length/width of a foto to be detected.) How can I improve the results of face
detection?
Thanks,
Christian
