Is it just images with beards having issues? I saw a while back where beards were confusing it for locating the chin accurately which affects how it fits into the red box. I made some changes and I thought it was working better. However, something could have chanegd again in the Adobe face detection. So even if I don’t make changes, things can start behaving differently if Adobe makes changes.
Anyway, Can you send me a few images where the scaling changes. I can look into it on Monday. Send the images to email@example.com
