https://bugs.kde.org/show_bug.cgi?id=375945

            Bug ID: 375945
           Summary: Face detection not scanning my images
           Product: digikam
           Version: 5.4.0
          Platform: MS Windows
                OS: MS Windows
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: Faces-Engine
          Assignee: [hidden email]
          Reporter: [hidden email]
  Target Milestone: ---

I recently installed DigiKam and having added the folder from my NAS containing
all of my images into my collection I navigated to Faces and clicked "Scan
collection for faces" apon clicking OK I get about 30 seconds of activity and
the progress bar progresses to 100% however no new faces are detected.

I have also tried specifying specific individual folders and see very similar
results (progress bar finishes faster for small folders)

Below are my current database statistics, I would expect face detection for
this number of photos to take several hours.

Install DebugView tool from Microsoft and when you run Face detection, report
here all debug trace printed by digiKam.

Debug as requested.

Debug log starts when DigiKam had finished loading, and saved once the
Facedetection reported itself to be finished (5 seconds after start)

I was running Facedetection against a folder containing 8.48GB of NEF files,
609 images

Acording to your log, it seems that you chose detect and recognise as option.
I'm concluding this from:

This problem was already solved in this bug:
https://bugs.kde.org/show_bug.cgi?id=375375

So, this is a known bug in 5.4 which is fixed for the upcoming release 5.5, I
woud say.

Seems to me like a duplicate, Gilles.

Struan,
can you test with the current 5.5 pre-release for Windows which is located
here:

https://drive.google.com/drive/folders/0BzeiVr-byqt5Y0tIRWVWelRJenM

Should be fixed.

Maria,

It can be a duplicate, but already fixed bug is for Linux, this one is for
Windows. So, we must considered not as a duplicate for the moment.
