This is pretty normal. Math equations can be substantially more complex
than English text. You have a lot more characters to recognize in
simple math (English letters, bars, upper and lowercase Greek letters,
arrows, infinity, fractions, set notation, maybe Hebrew letters...) than
you do in English text. And instead of everything being left-to-right,
some symbols can mean drastically different things if they're on top or
on the bottom of a divisor. And then there are infinite series and
integrals.
> What I'm looking for is an OCR program for Linux but better than Kooka
Kooka is a frontend for ocrad or gocr. gocr is better than ocrad. But
no matter what, Linux OCR = teh suck. Sorry to say it but it does. Use
Finereader if you have it; it'll give you much better quality than any
Linux engine.
> and optionally the possibility of "recognising" equations
This is a difficult problem, and I don't think there's anything out
there that does that right now. If you have math to enter, you'll
probably have better luck doing it by hand with (La)TeX or LyX. If
you're really ambitious, you can try to write something, but that'd be a
long run for a short slide unless you had thousands of pages of math to
OCR. (And you'd still have to proof it by hand afterwards!)
