Gamera: Optical music recognition in a new shell

An optical music recognition system has been completely overhauled and reformatted into a new framework called Gamera. The new open-source software is not only designed to recognize various music notations, including handwritten scores, but can be used to develop systems that can recognize many other structured documents. Gamera is intended to be used by domain experts with particular knowledge of the documents to be recognized but without strong programming skills. Gamera contains image processing and recognition tools in an easy-to-use, interactive, graphical scripting environment. Additionally, the system can be extended through a C++ and Python plugins.
