The Qgar® software system is aimed at the design of document analysis applications and is currently developed inside the QGAR Project at LORIA (France).

The system includes three parts:

  • QgarLib
    is a library including a set of C++ components implementing basic graphics analysis and recognition methods.

  • QgarApps
    is an applicative layer, including graphics recognition applications. All such applications are independent programs: They can be run using a command line (outside of the system) and be easily replaced when a more efficient algorithm is implemented.

  • QgarGui
    is a graphical user interface, developed using Qt. It provides an interactive access to all applications as well as means to display and manipulate (intermediate) results of graphics processings.
