Tree Rings Watermark

[Ery4z]

Hello everyone,
I was wondering if anyone has tried or is working on the implementation of this paper allowing the watermarking of the generated image

https://arxiv.org/abs/2305.20030

https://github.com/YuxinWenRick/tree-ring-watermark

I am quite surprised that I am not able to find much information about it online despite that it is not that recent. Is there some technical limitation related to the implementation of A1111 that prevent this feature to be added ?

In the conclusion of the paper it is stated that it is only needed to use the DDIM sampler and I guess to be able to provide the noize vector instead of a seed.

Am I missing an obvious point here ?
