Moire image watermarking

D R McCoy

This is an older project nicknamed ‘moire’, inspired by Googles Deepmind research into image watermarking with SynthID.

I have since done much more research and improved on the failures and shortcomings of this project, such as degredation at larger resolutions. I will upload this here eventually.

An invisible watermarking system; embeds a 64-bit payload that survives crop, resize, and recompression. Trained on the COCO 2017 118K dataset.
