The Document and Pattern Recognition Lab (dprl) is located in the Department of Computer Science at the Rochester Institute of Technology in Rochester, New York, USA. Our lab explores ways to improve the algorithms and tools used for automatic recognition and retrieval of information in documents, images, audio and video.
News (2015) (Earlier News)
- (Aug.) Prof. Zanibbi will join the Editorial Board of the International Journal on Document Analysis and Recognition (IJDAR) in September.
- (July) The NTCIR-12 MathIR Competition is starting soon - please consider registering and participating if you would like to help advance work in this emerging area of Information Retrieval (IR) research.
- (June) Houssem Chatbri, Kenny Davila, and Profs. Kameyama and Zanibbi have had their paper, "Shape matching using keypoints extracted from both the foreground and the background of binary images" accepted for publication at the International Conference on Image Processing Theory, Tools and Applications being held this November in Orleans, France. This work was completed during Houssem's visit to the dprl in Feb-March. He and Dr. Kameyama are from the University of Tsukuba, Japan.
- (June) To our surprise, Prof. Zanibbi's 'where, what, and how' summary of pattern recognition has appeared in a book about Big Data.
- (June) LgEval has been updated. This version fixes some bugs that missed valid segmentation edges, and corrects corresponding '*S' entries in .diff files. The new version can be obtained using git, by issuing:git clone http://saskatoon.cs.rit.edu:10000/rlaz/lgeval.git
- (May) Manish Kanadje has successfully completed his MSc project on indexing math lecture videos. His tool allows a user to create an index of video excerpts. Spoken keywords recorded on a laptop by the instructor can be used to generate candidate regions to include in the index. His keyword spotting results substantially improve upon Zack Miller's earlier work, and a related paper is in preparation (Poster).
- (May) The paper for Prof. Zanibbi's upcoming invited talk at CICM 2015 is now available: Math Search for the Masses: Multimodal Search Interfaces and Appearance-Based Retrieval. Awelemdy Orakwue (BSc. student) is a co-author on the paper. The paper has also been indexed in the arXiv.
- (Apr.) Profs. Charles Bigelow and Zanibbi have had their paper, "Analysis Of Typographical Trends In European Printing 1470-1660" accepted for presentation at the American Printing History Association (APHA) conference being held in October at RIT.
- (Mar.) dprl alumni Keita Wangari (MSc HCI, 2014) has accepted a position with Google Research in Mountain View, CA as a User Experience (UX) Researcher.
- (Mar.) Additional stories about the Tangent math search engine have appeared online: Making Search Engines Understand Math (EE Times), RIT Takes Lead in Formula Search Engine Racing (Campus Technology), and Demystifying Mathematics with Tangent Search Engine (Technology.org). The EE Times story was later picked up by ACM TechNews.
- (Mar.) Houssem Chatbri will be giving a talk on sketch-based retrieval in lecture videos on Friday March 4th at 12pm in GOL-1455.
- (Feb.) Today (Feb. 4) an RIT University News story on the Tangent math search engine appeared. The story features David Stalnaker, Nidhin Pattaniyil, and Kenny Davila.
- (Feb.) The research methods and writing text Writing for Computer Science (3rd ed.) by Justin Zobel will be published in the coming days. Prof. Zanibbi contributed some of the exercises in the new edition.
- (Feb.) The lab welcomes Houssem Chatbri (PhD student, Univ. Tsukuba, Japan), who will be visiting during Feb.-March. He will collaborate with Prof. Zanibbi on math retrieval research.
- (Dec.) Prof. Zanibbi will be an invited speaker at the 2015 Conferences on Intelligent Computer Mathematics (CICM).
- (Dec.) Nidhin Pattaniyil has received a travel award from the NTCIR-11 conference organizers.
