The Document and Pattern Recognition Lab started in Summer 2007. We work on a variety of projects, applying pattern recognition and machine learning to extracting and searching information in documents and videos. Our work has appeared in top venues including TPAMI, CVPR, and SIGIR, and some of our projects are used by groups around the world (e.g., the Tangent formula search engine, and the CROHME handwritten math recognition benchmark).
Lately we have been focused on the recognition and retrieval of mathematical notation. Our work in this area is being funded by the National Science Foundation (NSF) and the Alfred P. Sloan Foundation. University students of all levels (BSc, MSc, and PhD) from the Computing and Imaging Science colleges at RIT have worked in the lab. See the Members page for pictures and a list of all students who have worked in the lab.
Examples of our projects, along with links to our publications, data, and software can be found on the Resources page.
