ok thanks for you answer, I guess i won't be able to make it work for my pictures.

But out of curiosity, how could you train your network for only the artwork?
Taking the survey pic of AKH, cropping to only get the artwork, dividing them into 64x64 blocks and then do the same with low quality pic and 16x16 blocks and then train it with all the blocks?

Basically yes - except there is no need to generate the low quality data as the training process downsamples the high res for you.

I have processed the full set with this 3rd version. If anyone wants to host this set (from CCGHQ or elsewhere) please let me know.

Have you looked into Waifu2x? They have been working on a similar but different feat as far as deep learning art upscaling. While their goal is primarily art focused there might be something there to help.

Here is the same inital test you ran with their program.

Before:

After:

Your results look very promising and a huge step up from the inital run.

I love that result, especially on the art. I'll definitely have a look when I get back from my holiday.
