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.
