And so I asked the friendly nerds of Twitter. I showed the original typewriter car scan, added my blurred-then-sharpened photo as a pathetic comparison, and asked: what is the latest in demoireing? Is there some new tech that could help me?

I didn’t get any obvious machine learning hints. Many people responded with downright resignation: what you did is still the best out there. But a friend of mine – a neuroscientist from Utah – had an answer I didn’t expect.

“You don’t need ML,” Bryan said. “What you need is inverse FFT.”

This is such a wonderful story about learning how to work with old technologies. I appreciated every word of this.
