gImageReader is a front-end for Tesseract Open Source OCR Engine. Tesseract was originally developed at HP and then was open-sourced in 2006.
Basically, the OCR (Optical Character Recognition) engine lets you scan texts from a picture or a file (PDF). It can detect several languages by default and also supports scanning through Unicode characters.
However, the Tesseract by itself is a command-line tool without any GUI. So, here, gImageReader comes to the rescue to let any user utilize it to extract text from images and files.
