I only noticed because I considered using the model myself, until I saw the licensing. Best of luck!
By the way, your aseprite plugin inspired me too. I think you created it with Pixel Art Diffusion. In the next version, I will add Pixel Art Diffusion module in PixageFX Studio with a model that has no license problems. It has already been something users have been demanding for a while. Thanks again.
I've actually been training and releasing models for about 10 months now, all trained on my own artwork and other licensed assets, nothing to do with Pixel Art Diffusion (though KaliYuga is a friend and inspiration). You might actually be interested in this downscaling algorithm I designed myself, its not quite as good at turning things into pixel art as Pixelization, but it is MIT licensed. https://github.com/Astropulse/K-Centroid-Aseprite
Thank you for detailed information.
Although artificial intelligence is very exciting, I am much more satisfied with the Pixelate algorithms that I have prepared completely at PixageFX. Because it gives undesirable results in artificial intelligence models. For example, for the Deeppixelate module to be successful, the input image must also be suitable for it. It also distorts colors and values such as gamma/contrast. I went through the link you gave and it's pretty clever. But all the downscale algorithms I've seen don't scrutinize the image much. In addition, the entrance image should have some preliminary preparation. Usually this part is skipped. the algorithm in the link seems to have just destroyed antialias. This is an algorithm that has already been available in PixageFX from the very beginning.
