I've personally used gocr and ocrad with varying levels of success. It's
not perfect, but with some image preprocessing w/ImageMagick you can
automate all kinds of text extraction from random images.

In your case, however, PDFs are trivial to extract text out of -- assuming
the PDFs aren't actually just storing images. Even so, I've been able to
rasterize image PDFs and extract text out of them as well.
