There are multiple galleries and sliders in the original post but these two seemed relevant to DFU.This was upscaled using ESRGAN after trained using a fork of BasicSR by victorca25 of the GameUpscale discord community. The training dataset consists of high resolution pinups and paintings with smooth, mostly textureless finish from DeviantArt & other imageboards. After 200,000 iterations, it transfers the painting style well while trying very hard at anti-pixelation of the input images, to varying degrees of success.
