The idea is similar to HiresFix from A1111. The image is first upscaled with ESRGAN model and then split into tiles and processed using the Klein model one by one. The tiles are then stitched back together and, optionally, color corrected. Since the original image is passed to Klein as reference, it helps preserve the image structure and style, while significantly reducing upscale artifacts and adds small amount of detail to the final image.For best results correct errors and inpaint small details before upscaling.Note: ComfyUI variant requires <a target="_blank" rel="ugc" href="https://github.com/Steudio/ComfyUI_Steudio">Steudio node pack</a>.
