HADARA

A Software System for Semi-Automatic Processing of Historical Handwritten Arabic Documents

The HADARA System is a modular toolkit for processing historical documents. It provides particular support for handwritten Arabic documents. Several processing techniques are available as different modules that can be chained up to complex processes. Built upon these modules and a powerful framework, the HADARA System also contains several applications and tools for users such as historians and linguists as well as for developers and researchers in the field of document image analysis, image processing, and pattern recognition.

The source code of the HADARA System is designed to be interpreted by Mathworks' MATLAB® environment.

Applications

Among the applications of the HADARA System are:

HADARA Tool (main application):
  • annotation of documents
  • word spotting
  • transcription searching
SetupGUI:
  • create configurations consisting of processing chains and module settings
  • define the information flow between modules
Palaeography GUI:
  • add palaeographic comments to document images and any kind of pre-annotated segments
  • can re-use annotation files from HADARA Tool
Writer Analysis GUI:
  • perform several kinds of writer analysis on document images
  • (not yet open sourced)

For more details about these applications and other tools, please refer to the project documentation (available soon).
