Traeyu Posted March 2, 2019 Posted March 2, 2019 Hi guys, I don't think anyone has mentioned this as it's pretty new and a bit complicated. ESRGAN (Enhanced Super-Resolution Generative Adversarial Networks) has been used for video games graphics to improve textures and pre-rendered graphics but it could be used to make higher quality marquees, titles, etc. It essentially uses AI that has been trained with a bunch of images to try and guess what the image should look like at a higher resolution. There are some different settings and trained image models that you can use to get different effects. It's not a perfect science but I've found it can make some amazing stuff. You do need a pretty decent gpu to run this, just an fyi. If you would like to try it out you can find more information here: https://github.com/xinntao/ESRGAN It's a little complicated to set up if you don't have any prior python or programming experience but here is a simpler tutorial to get things working as well as some pretty awesome examples of it's uses with video games: https://www.resetera.com/threads/ai-neural-networks-being-used-to-generate-hq-textures-for-older-games-you-can-do-it-yourself.88272/ & here: https://esrgan.blogspot.com/2019/01/blog-post.html I haven't tried more than a couple of the trained models but manga109 seems to work really well for illustrated graphics without adding as many new artifacts: http://www.mediafire.com/file/w3jujtm752hvdj1/Manga109Attempt.pth.zip/file Text can be tricky depending on the model you use. The manga109 model doesn't seem to do as well with small text as some of the other models so you may have to try different ones depending on the type of art or text. Example from the ESRGAN site: My Examples: Original: ESRGAN (Manga109 Model): It can work on some pretty small original art as well: ESRGAN (Manga109 Model): If you added a sharped filter in Photoshop the art would pop even more. Hope you all can make some use of this!
Rowr14 Posted March 3, 2019 Posted March 3, 2019 This is very cool. Should be pretty handy in the future for scaling up art when we are all running at 4k. Also pretty useful for cabinet art I would think. I've been using waifu which has some decent results, I might give this a look.
Traeyu Posted March 5, 2019 Author Posted March 5, 2019 Thanks for the tip on http://waifu2x.udp.jp, I had no idea this existed. I tried it out and it actually does a pretty good job, not as good in some aspects but definitely easier to use.
