Hey, Thanks for reporting issues back to Nextcloud Face Recognition. Please, try to complete this report in detail so we can help you easier. :smile:

Make sure you read all the documentation, and the FAQ, and that the issue has not been reported before. :wink:

Expected behaviour

Afetr the analysis, ask the user to recognize the faces

Actual behaviour

Not all the faces discovered are available for recognization

Steps to reproduce

  1. Launch analysis occ face:background_job
  2. Waith for ending
  3. Check how many faces are discovered with occ face:stats
  4. Start recognize your friend with the gui
  5. Check the difference, actually I have 7136 faces found, but recognized only 289

You might try slowly dialing back the Confidence until you get the right balance of accuracy and clustering. The difficulty is that if you lower confidence, you might end up with more clusters that have more than one person, and especially young children.
