In an effort to restore them as much as I could, I used a combination of waifu2x ("Single-Image Super-Resolution for Anime-Style Art using Deep Convolutional Neural Networks"), Clip Studio Paint resize/cleanup tools, and manual cleanup done by hand. Unfortunately, the red text on the title page was a lost cause. If anyone can decipher solid red rectangles please contact me lol. Source: about 1 year ago

Maybe this would help. There's also an app version of it. Source: about 1 year ago

I would recommend putting it through an upscaler beforehand, it seems a bit small. Source: over 1 year ago

Http://waifu2x.udp.jp/index.html found this image upscaler from https://www.reddit.com/r/FireEmblemHeroes/comments/a51f0k/i_turned_yusuke_kozakis_artwork_into_a_high/?st=JPIZKYIB&sh=f12f76fe a while ago, perhaps that would be the closest if IS doesn't release anything. Source: over 1 year ago

You can make it bigger for print by using by using an Japanese AI image enlarging tool. Source: over 1 year ago

That doesn't mean you have no options though, playground.ai and leonardo.ai are both stable diffusion powered with simple interfaces, just on the cloud. MacOS has DiffusionBee which is pretty simple. Easy Diffusion is a thing too. Source: about 1 year ago

You can run with cpu but won't worth. Try online solutions like colab or rentpod or use online AI generators like playground.ai. Source: about 1 year ago

So, this computer won't run Stable Diffusion locally, but just about any modern device can get on the internet and connect to other computers that can run Stable Diffusion, through all the various SD based websites like Stability's own website or playground.ai or in the cloud through something like a Collab notebook. I just want to be sure you understand that running SD locally on hardware isn't your only option... Source: about 1 year ago

THX! I am a newbie, using playground.ai. With the promt, I have really ugly results with deformed bodies... What did I make wrong? :). Source: about 1 year ago

The AI Generators (on PC, websites) that I use include Dall-E 2, Playground.ai, Night Cafe, Hotpot.ai, Stable Diffusion, and Artbreeder. I also use Free Domain pictures from Freepik. On my mobile I use Wonder.ai. Source: over 1 year ago
