ocr using a command line tool

I'm looking for a windows command line tool th开发者_开发技巧at does OCR. Specifically I'm trying to extract the number from this image: http://img691.imageshack.us/img691/6075/wantocr.png

I've tried tesseract and found it quite poor imho. Perhaps it needs settings that I'm not aware of. I've tried a few others and they too were pretty poxy. Some of the online ones were quite good but I really need it to be a command line.

I would really appreciate posts that accurately extract the number from the image in the link above.

many thanks, Fidel

p.s. I could do some very simple image processing like converting it to blank and white etc.

As some of the links here were rotten after the years: I just stumbled across this topic and found Tesseract to be quite good nowadays! It's FOSS, in constant development and now on version 4.

https://github.com/tesseract-ocr/tesseract

installation links to binaries for Windows as well. And then

tesseract image_name.png out.txt

Yielded some useful things already!
