A Handwriting Understanding Environment (HUE) for rapid prototyping in handwriting and document analysis research

HUE (the Handwriting Understanding Environment) is a software framework for handwriting and document analysis built around a two-level programming model in which components are implemented in a system programming language (typically C++) and are connected together into prototype systems using the scripting language Tcl Tk. HUE is an extended version of TABS (a previous handwriting analysis framework), and incorporates the authors' experience of using TABS for around 2 years in data-intensive handwriting and document analysis research and evaluation. HUE currently contains 94 C++ components, 7 native data types, 11 custom-built Tcl Tk packages, a novel dynamic user interface, and several demonstration systems implemented as Tcl scripts.
