The watermark detector doesn't work with Gemini 2.5 and Gemini 3 pro

[GabrielGarcia1995]

I tested the watermark detector on several images generated with Gemini 2.5 and Gemini 3 Pro. It didn’t work for me. Specifically, I evaluated 10 synthetic images and 10 real images. In all cases, the watermark detector returned a “False” result, with a confidence level below 0.1.

After installation, I run this code:
python src/extraction/robust_extractor.py detect folder_images/image.png --codebook artifacts/codebook/robust_codebook.pkl

Am I missing something? Thanks in advance

Hi @GabrielGarcia1995 We are releasing a V4 that will hopefully beat the Pro image watermarks too
