Python-tesseract is a wrapper class for OCR that allows any conventional image files (JPG, GIF, PNG, TIFF, etc.) to be read and decoded into usable text.

Tesseract is advertised as the most accurate open source OCR engine available. It was developed at HP Labs between 1985 and 1995 and then remained dormant until 2006 when Google revived the project.

For more information, please see the Python-tesseract page or the Tesseract page.
