Thanks, Mike.

since accoring your explanation this an expected behaviour of the currently
used model, rather than a bug, I've set the status to resolved-intentional.

Cheers,

[digikam] [Bug 420128] New: Poor result of face detection (7.0.0. beta2)

Bug ID: 420128
   Summary: Poor result of face detection (7.0.0. beta2)
   Product: digikam
   Version: 7.0.0
  Platform: Other
OS: MS Windows
Status: REPORTED
  Severity: normal
  Priority: NOR
 Component: Faces-Detection
  Assignee: digikam-bugs-n...@kde.org
  Reporter: sseilm...@web.de
  Target Milestone: ---

Created attachment 127568

samples

I've ran face detection several times on tousands of photos whith very poor
results

For instance, in the attached picture (1) I'd expect the algorithm to detect
6-7 faces.
In the attached picture (2) I'd expect the algorithm to detect 12 faces.
On my System (intel I5-3500, 16 GB, Win x64) only 3 are detected in 1 and none
at all in 2.

I've varied the sensivity between 0 and 100 (every ten), to no avail.
I've tried all possible variations of settings in the maintenance tool as well.

After the face detection is finished, there is no "unknown" tag in the left
people-sidebar, but when I open the pictures in the albums view and enable
"show faces tag", the mentiones 3 tags are visible.

Since I mainly work on b/w pictures it might be related to that.
Also, it may be same as bug 415561?


STEPS TO REPRODUCE
1. Create new database
2. Create new album with attached images
3. Scan for faces
