Interesting Observation - Facial Recognition

[Michael Miller]

Hi Paul,
Yes, it can be a bit difficult to remove overlapping face boxes.  Here’s a trick isolate the boxes so you can remove the one you want. Unfortunately, it can be a tedious process depending on how many images have overlapping face boxes.


  1.  Find the file name of image with the overlapping face boxes by opening up the Properties tab in the right sidebar.
  2.  Right click on the filename at the top (not the full path), click Select all
  3.  Right click again on the filename and select Copy
  4.  Close the right Properties tab
  5.  Open the left People view and go to the Unknown branch in the tree. This is assuming both faces are Unknown. If both faces have the same or suggested tag, then click the tag name under the People branch.
  6.  Using either the filter tab in the right sidebar, or using the filter icon at the bottom, open the right filter view.
  7.  In the Search… field in the filter view, paste in the file name from step 3.
  8.  You should now just see the faces for this image.
  9.  Delete the image boxes you don’t want.

I know this can be tedious, but it will work.

Cheers,
Mike

Having previously used Picasa for my photo storage I am migrating to digiKam. Using Windows 11 digikam 8.6.0

Whilst Picasa identified faces, many of my "faces" are manually annotated with the selection boxes often larger than the immediate facial area, the data being stored in the metadata.

digiKam seemed to import this information fairly successfully but nonetheless I set it to Tools->Maintenance->Detect and Recognize Faces.

It took most of the day (c. 69k items) but at the end an interesting observation was that in perhaps a couple of dozen instances an area within the originally manually applied selection was incorrectly identified. The interesting thing being this incorrect identification was usually either a sibling or child of previously identified person. Genetic similarity confirmed perhaps?

My only difficulty was trying to delete this inner area, as soon as I moved mouse towards the "Confirm/Remove/Ignore" box the outer area was selected. In the end I resorted to typing "Ignored" without moving the mouse.

Have I perhaps missed the keyboard shortcut for this process.

Cheers

Paul
