Lipi Toolkit

Welcome to


An offshoot of our work in handwriting recognition is the open source Lipi Toolkit, a collection of tools and algorithms for building handwriting recognition engines. The toolkit is being used internally as well, for example: for gesture recognition for the Gesture Keyboard, a text input solution for Indic languages.

Our research in this area focuses on:

  • Graphical tools for handwriting data collection

  • Scripts and graphical tools for the analysis of recognition accuracy and errors

  • Algorithms for handwritten shape recognition, build scripts for building engines, and support for UNIPEN 1.0 and a standard shape recognition interface.

  • The toolkit focuses on: supporting collaborative HWR R&D in academic and industrial settings, tools for user interface research, supporting commercial HWR development.

  • Promotion of standard ink representations and interfaces.

  • Promotion of sharing & reuse of tools, algorithms, code and handwriting datasets.

  • Promotion of product and solution development.

More information on Lipi Toolkit is available at: lipitk.sourceforge.net
