This package contains an OCR engine -
libtesseract and a command line program -
Tesseract has unicode (UTF-8) support, and can recognize more than 100 languages
out of the box.
Tesseract supports various output formats: plain-text, hocr(html), pdf, tsv, invisible-text-only pdf.
You should note that in many cases, in order to get better OCR results, you'll need to improve the quality of the image you are giving Tesseract.

Tesseract can be trained to recognize other languages. See Tesseract Training for more information.

In 2005 Tesseract was open sourced by HP. Since 2006 it is developed by Google.
