Vectorizing woodcuts with Waifu2x and Potrace
Woodcut from A Description of the Northern Peoples
I thought this might help me in digitalizing the book, for getting the images to a better format!

Original JPG (512x236, 56 KB)

After Waifu2x (1024x472, 426 KB)
Ran the original jpeg on waifu2x-tfjs with 2x res.

After Potrace (409 KB)
Ran the waifu2x result in a JS port of Potrace.
