Diagram Recognition Laboratory


Contact Information

Location: Goodwin Hall Room 747
Phone: (613) 533-6000 ext. 78234

About the Lab

Our labs' goal is the development of technologies for automating the recognition of diagrammatic notations such as maps, blueprints, mathematical notation, UML diagrams and sheet music. Our lab also works toward the goal of developing tools similar to those available for programming language compilers, so that diagram recognition systems may be created through joining well-understood components, rather than having to be built from scratch.

Currently we are focusing on map recognition and recognizing the symbol layout of tables, business cards and mathematical notation.

Our members have worked on many levels of the problem, including symbol recognition, diagram interpretation, and interfaces for entering diagrams on-line. One of these interfaces, the Freehand Formula Entry system, is available for download from the 'Software' link above.

Please feel free to contact members of our lab (listed on our 'Members' page) if you have any questions.

The Diagram Recognition Lab associates with the Software Technology Lab at Queen's University.
