There was a somewhat scary case study on the web a few years ago (not
sure if it's still out there, haven't been able to find it) It seems to me that a better tool could solve the
issue. One that
could display the OCR:ed content only and the scanned content
only when desired, for instance when you suspect an error.
Is there such a reader? Is the content organised to make it
possible.
I haven't seen one.
I did start trying to write an heuristic probabilistic OCR one 25 years
ago. The idea being to overlay the OCR'd (displayed with matching
fonts) over the scanned content. ...
