Not Here.
I was once fooled by the following logic: 'well it was printed in bilevel,
so there's no sense in going above that'. What's wrong there is that
there's need for subpixel information like for things that don't sit exactly
on a pixel but a fraction to the side of it, and certainly for this: curved
letters. I choose 300dpi grayscale but if I had to-had to use bilevel I'd
go above 600dpi possibly all the way to 1200. There's even ways to
transform that back to 300dpi grayscale if need be, like for when that
super OCR program that we all need finally gets written.
Is there an open-OCR effort in Linux I wonder?
