Hi Neil, Faruk's advice is good, and additionally you could tighten the digits whitelist to only include numbers (digits also includes - and .), presuming you're sure that's all you'll see.
You could do that by using a command like this: tesseract IMG_20140325_100806.jpg test1 -c tessedit_char_whitelist=0123456789 Tesseract is designed for printed pages, though, so it won't do well for very skewed or crumpled images. If you can fix them before passing to Tesseract, though, then it should work fine. Nick -- -- You received this message because you are subscribed to the Google Groups "tesseract-ocr" group.
