The Document and Pattern Recognition Lab (dprl) explores ways to improve the algorithms and tools used for automatic recognition and retrieval of information in documents.

### News (2013)

• (Dec.) The lab welcomes Zack Miller to the lab. For his MSc project, Zack will be working on keyword spotting in audio for the AccessMath project.
• (Dec.) The lab welcomes Nidhin Pattaniyil to the lab. Nidhin will working on combined text and math search for his MSc project.
• (Nov) Siyu Zhu has successfully defended his PhD dissertation proposal. Well done, Siyu!
• (Nov) Lei Hu has successfully defended his PhD dissertation proposal. Congratulations, Lei!
• (Oct) Kenny Davila's paper describing a system for image-based retrieval of mathematics in lecture videos has been accepted for presentation at the 2013 IEEE WNYIP conference being held at RIT in November.
• (Aug) David Stalnaker has successfully defended his MSc thesis, Math Expression Retrieval Using Symbols Pairs in Layout Trees.

• (May) Congratulations to Matthias Reichenbach, who has successfully defended his MSc project on the effect of rendering math expressions on relevance assessment for math search.
• (May) Congratulations to Kenny Davila Castellanos on successfully defending his MSc project on image-based search of whiteboard notes in math lecture videos. Kenny will start his PhD in the DPRL for the AccessMath project this summer, co-supervised by Prof. Zanibbi and Prof. Ludi.
• (May) Congratulations to George (Huaijin) Chen on successfully completing his senior undergraduate Imaging Science project on using inpainting to hide text and prevent OCR attacks against Video CAPTCHAs.
• (May) Prof. Zanibbi has been awarded an NSF REU grant, which will be used to fund undergraduate researchers in the DPRL lab during summer 2013.
• (May) ImagineRIT will be held on Saturday, May 4. The lab will be demonstrating the ${m}_{\mathrm{in}}$ math search interface in the atrium of the Golisano college.
• (May) Lei Hu and Siyu Zhu had papers describing a system for detecting text in patent document images (Siyu) and using shape contexts to segment handwritten mathematical symbols (Lei) accepted for publication at the International Conference on Document Analysis and Recognition being held in Washington, DC in late August.
