command line scanned pdf to text

[Cheryl Homiak]

I am sure tiff is supported. It is really strange. I get what look like words and what I get is the same every time I do a scan of the same image but they are nonsense. I even tried adding the designation for English thinking somehow it wasn't using English but got the same results. I know the image file is okay because it comes out fine using ABBY FineReader Express on my Mac.

and the meditation of my heart
be acceptable to You, Lord,
my rock and my Redeemer.

I am asking this because I have tried to use tesseract a couple of times with tiff files and have gotten mostly gibberish so obviously I am doing something wrong. I am running debian testing if that makes a difference.

On pages that are just prose, it probably does about 99% accuracy. Even on pages where that are 2 columns of prose, it does really well if you tell it to look for that. Somebody sent me a pdf of the same book done with a professional OCR program for Windows. The results are approximately equal. Tesseract may lack the bells & whistles of commercial products but for accuracy, it's pretty good.
