Re: OCR

Hi,


Many great solutions exist now for OCR on Linux.

1. Free software: gimagereader (uses Tesseract), works all right, as
well as gocr

2. Other free solution: Hypra developed Ocrizer. If you install it, you can:

- from a shortcut, running the scanning process, the characters
recognition, and opening Writer. The shortcut is integrated
automatically in Hypra systems, using MATE and Compiz. As you probably
not installed it, you will need to implement the binding by hand. The
command to add to your desktop environment and to give a binding would
be: sh -c "/usr/bin/ocrizer -s -d ~/Documents"

- if using MATE, you can install 
mate-accessibility-ocr-integration-caja and a command in the context
menu will enable you to OCR a n image file (eg a PDF shipped on the
Internet), via different means.


Note that this tool is based on Tesseract.


3. Paying solution:

a) Abbyy Finereader (proprietary): for 150 euros, Abbyy provides a
commandline tool. Install it, run it via a script you create or
manually, and you can use Finereader engine in Linux. The license is a
key, you can get online, it enables you to be run on One machine and you
can OCr 12000 pages per year (the counter reloads each year).


If you buy it but want to have a script, you can install it, then
install ocrizer-finereader from Hypra. It will bring the features I
described above, but based on the Finereader engine instead of Tesseract.


b) Finally, if you want to support a social-impact company and get
support to implement your OCR installation, and if you want to bypass
the anual 12000 pages limitation, you can buy Finereader to Hypra: just
a mail, then a payment by transfer and they send you the license key.
The price is 180 euros, because the anual 12000 pages is missing.


To get Hypra repos (for suggestions 2 and 3 a):

Note that only Jessie works now, devs for Stretch are in progress. But
Hypra can assist you installing Finereader and Ocrizer on another
release of Debian (it's paying but possibe).


Hope it helps.



Cheers
