Are there any error correction systems that would make a 3cm x 3cm hole anywhere on the page still allow the full page to be completely recoverable?
Or "holographic" error correction, where even if 90% of the page is gone, you could still get the "gist" of it somehow? (I'm not sure what I'm asking for mathematically, but probing for ideas that are out there.)
- deoxxa 5y agoErasure coding (particularly fountain codes) are what you'd want to use.
- mbreese 5y agoYou’d have to be clever about the physical distance between overlapping codes. You’d hate to see a 3cm artifact (cut, stain, spill, etc) take out a whole unit/block. (Assuming you’d print multiple blocks on a page.)
