I have a book I want to read onscreen. It is scanned at 200 dpi monochrome (I still don't know what went wrong in the scanner driver, I remember setting it to grayscale, but cannot afford the time to scan again), so it is hard to read. I OCRed it with Acrobat Acrobat Pro, and it went reasonably well. But the result is either something called "Searchable image" or "Clearscan". I like the fact that the layout is preserved, but the problem is that the text is shown as it was scanned, so it is difficult to read onscreen. Besides, the whole book takes up 70 MB.
Here you can see what the already recognized text looks like:
I tried other OCR programs, but (besides hogging 100% processor time and memory for 2 min per double page) they all recognized the text, leaving the figures completely out. I don't care that much about the layout and the typography, but the figures are important (I don't need the text labels in the images to be OCRed). And I think that if it were to use ASCII for the text and images for the figures, the size should drop considerably.
So is there a way to ditch the images of the text and use the OCRed version for reading while keeping the figures in their places? I'd prefer the end result to be a PDF file, but I am open to other formats too. I know I could do it manually by pasting the OCRed text in word and capturing screenshots of the images, but this is too much work for 520 pages.
