This project is amazing! These images are light years ahead of what we had in the old days.

austinio7116, please update your first post with a current before and after shot. Also leave up the pics you have now so we can see the progress you've achieved.

I tried to use Waifu 2x to better the image quality of CMA low-res pictures but they came vastly inferior to your image quality

Yes, I think my final results are better for magic cards than Waifu, although I do think Waifu is great for anime art.

Here's the low res and upsampled versions of one of the nicer results on the art from XLN:

Here are some sets of images showing the low res, the super resolution - and now the newly released scans for comparison:

Nice comparison. IMHO, if you are using mobile device not greater than 9" display, the super resolution will do the job (also the file size is very friendly for mobile devices). The card scans is much suited to PC with big monitors...

Here is a comparison with other upsampling methods:

The pictures are: Low Res, Bicubic interpolation, Waifu 2x (just the standard web version run twice - not specially trained on Magic cards), My DCGAN, HQ scan

I think the colour depth, vibrance and colour consistency can be better with this method as printing/scanning is bound to reduce this a little, however the detail and sharpness can never be as good as the scans at 300dpi.

If I can find 370x265 CMA images from Wizards I should be able to upsample them.

I can't see 370x265 images, only lower Res gatherer ones, perhaps that's why your Waifu upsampling was so noticeably inferior. I can try upsampling the gatherer images but would not expect to get such good results, the network is specifically trained on, and so optimised for 370x265 input.
