Today I learned that michiru fanart will consistently trip ai detectors
So I was running art through ai detectors for fun and noticed a pattern, any art of michiru would regularly be seen as 25% chance to be ai, while other stuff I draw is in the 1%, so I looked deeper.
Turns out her raccoon mask is partially to blame. AI detectors look for hard geometric transitions on faces. Because AI generators often struggle with drawing clean lines or accurate faces, detectors are sensitive to facial zones. Michirus mask pattern is a sudden shift in face tone which trips the detector.
Now her color palette also trips it, the eye colors she has are also common place on ai generated characters.
Lastly, art of her is in ai databases already. Some ai models were heavily trained on anime image boards. Now around the time when most of these ai’s were being trained BNA was decently popular, leading to michiru appearing on these boards a lot. There’s also a fair bit of ai generated michiru art.
In conclusion michiru trips ai detectors purely due to her appearance.
