Describe the Bug

Hello, I’m encountering an issue with the Recognize app in my Nextcloud instance. After running the face detection and classification process using:

sudo -u www-data php /var/www/nextcloud/occ recognize:classify

I noticed that every face detection attempt results in very low confidence scores (around 0.2–0.3) and is skipped. Here’s a snippet of the output:

Face results for 24940 are in Face score too low. continuing with next face. Result for /leandro/files/Fotos/20180903_180749.jpg(oc_tmp_JFBVJE-.jpg) = []

This pattern repeats for all my photos, so no faces are actually recognized.

I have already tried: βœ… Running recognize:download-models βœ… Re-indexing with recognize:recrawl βœ… Running recognize:classify again

All commands execute without errors, but no faces are successfully recognized.

Is there anything else I should check to ensure proper face detection? Thank you for your support!

Expected Behavior

Expect to recognize faces in the images

To Reproduce

βœ… Running recognize:download-models βœ… Re-indexing with recognize:recrawl βœ… Running recognize:classify again

Hello, can you share files we can run recognize on, to confirm if this is a bug or limitation of current models and then it will be a feature request?
