The three images attached below (pasted together into one) were generated with the same settings (0.2, 0.025), and IMO pretty easy to read (it may help for some to either lean back a bit, or better yet, look at them at a sharp angle). What I'd really like to know is if they really could resist an advanced OCR engine, or if I'm, in fact, seriously underestimating the problem? Well, that's the next step, anyway, and I plan on running it through as many OCR's as possible, for good measure.
