Nice. An artist can run their visual art image through this tool. The tool produces a new version of the image that is almost identical to the human eye, but will prevent unethical, extractive AI like Stable Diffusion or Midjourney from learning the artist's style, so that their style can't be stolen and copied. Then they can freely post images online without having to worry that some asshole company will co-opt their art style.
They do warn that AI advances quickly and this particular tool will most likely not always be effective. However, I think the effort is commendable, and this tool or some future variant could put enough of a barrier in place that it is no longer cost-effective for lousy AI companies to steal from artists.
