Using the Gamera framework for the recognition of cultural heritage materials

This paper presents a new toolkit for the creation of customized structured document recognition applications by domain experts. This open-source system, called Gamera, allows a user, with particular knowledge of the documents to be recognized, to combine image processing and recognition tools in an easy-to-use, interactive, graphical scripting environment. Gamera is one of the key technology components in a proposed international project for the digitization of diverse types of humanities documents.

Optical Music Interpretation

A system to convert digitized sheet music into a symbolic music representation is presented. A pragmatic approach is used that conceptualizes this primarily two-dimensional structural recognition problem as a one-dimensional one. The transparency of the implementation owes a great deal to its implementation in a dynamic, object-oriented language. This systemis a part of a locally developed end-to-end solution for the conversion of digitized sheet music into symbolic form.
