Tesseract OCR Optical Character Recognition for Linux
The best Optical Character Recognition Softwares is Tesseract OCR. Definition of OCR is a technology that allows you to convert scanned images of text into plain text. This enables you to save space, edit the text and search/index it.
Tesseract OCR is the most accurate, under Linux now they lack graphical interface (GUI), which is a very important usability feature for a typical desktop user.
The current version of Tesseract in the Ubuntu repository is a command-line-only tool. After successful installation, the command to use is tesseract <path to image> <basename of output file>. Tesseract will automatically give the output file a .txt extension. If you have installed the language specific data files from one of the tesseract-ocr-??? packages, you can give an -l option followed by the language code.

Tesseract OCR Review in Linux
Tesseract is probably the most accurate open source OCR engine available. Combined with the Leptonica Image Processing Library it can read a wide variety of image formats and convert them to text in over 60 languages.
It was one of the top 3 engines in the 1995 UNLV Accuracy test. Between 1995 and 2006 it had little work done on it, but since then it has been improved extensively by Google. It is released under the Apache License 2.0.
Tesseract was originally designed to recognize English text only. Efforts have been made to modify the engine and its training system to make them able to deal with other languages and UTF-8 characters. Tesseract 3.0 can handle any Unicode characters (coded with UTF-8), but there are limits as to the range of languages that it will be successful with, so please take this section into account before building up your hopes that it will work well on your particular language!
Tesseract 3.01 added top-to-bottom languages, and Tesseract 3.02 added Hebrew (right-to-left). Tesseract currently handles scripts like Arabic with an auxiliary engine called cube (included in Tesseract 3.0+)
NOTES: If you are not familiar with command using linux Terminal, you should install YAGF –the GUI for Tesseract OCR.
