Tesseract is an optical character recognition engine for various operating systems.[5] It is free software, released under the Apache License.[1][6][7] Originally developed by Hewlett-Packard as proprietary software in the 1980s, it was released as open source in 2005 and development was sponsored by Google in 2006.[8]
In 2006, Tesseract was considered one of the most accurate open-source OCR engines available.[7][9]
