Tesseract (software) Tesseract is an optical character recognition engine for various operating systems.[2] It is free software, released under the Apache License, Version 2.0,[1][3][4] and development has been sponsored by Google since 2006.[5] Tesseract is considered one of the most accurate open source OCR engines currently available.[4][6] Tesseract up to and including version 2 could only accept TIFF images of simple one column text as inputs.
These early versions did not include layout analysis and so inputting multi-columned text, images, or equations produced a garbled output. Since version 3.00 Tesseract has supported output text formatting, hOCR positional information and page layout analysis. Support for a number of new image formats was added using the Leptonica library.
The initial versions of Tesseract could only recognize English language text. If Tesseract is used to process right-to-left text such Arabic or Hebrew the results are ordered as though it is left-to-right text.[10] Libtiff. Evernote Optical Character Recognition « The BRITE Blog. I use Evernote to help organise my work and personal life. It is a very simple app and makes it easy to synchronise notes between my iPad, smartphone and home and work PCs. There is a useful hidden extra which I have only recently become aware of: Evernote will perform Optical Character Recognition (OCR) on your photos. Evernote enables you to take a photograph as a note and then categorise it or tag it as you would with a typed note.
Once your photo is uploaded to the Evernote server it will perform OCR and therefore allow you to search for any text contained in that note. You can do the same with a photo imported from you photo library. This could be really useful for people with literacy or memory difficulties who record information using photographs. Rather than having to visually scan through all their photographs to find the one they need, they can simply type a key word and Evernote will find that photo for them and highlight the searched for word.
