The Ninth International Workshop on Graphics Recognition (GREC2011), organized by IAPR TC-10 (Technical Committee on Graphics Recognition), was held just before the 11th International Conference on Document Analysis and Recognition (ICDAR), Beijing, China (see ICDAR 2011 report in this issue). It was chaired by Young-Bin Kwon (General Chair, Professor, Chung-Ang University), Jean-Marc Ogier (Program Chair, Professor, University of La Rochelle), and Jaehwa Park (Local Arrangement Chair, Associate Professor, Chung-Ang University).

The GREC series of conferences is the main event of IAPR TC-10. They provide an excellent opportunity for researchers and practitioners at all levels of experience to meet colleagues and to share new ideas and knowledge about graphics recognition methods. Graphics recognition is a subfield of document image analysis that deals with graphical entities in engineering drawings, maps, architectural plans, musical scores, mathematical notation, tables, diagrams, etc.

The previous workshops in the series are GREC'95 in University Park, Pennsylvania, USA (LNCS Volume 1072, Springer, 1996), GREC'97 in Nancy, France (LNCS Volume 1389, Springer, 1998), GREC'99 in Jaipur, India (LNCS Volume 1941, Springer, 2000), GREC01 in Kingston, Ontario, Canada (LNCS Volume 2390, Springer, 2002), GREC03 in Barcelona, Spain (LNCS Volume 3088, Springer, 2004), GREC05 in City University of Hong Kong, Hong Kong (LNCS Volume 3926, Springer, 2006), GREC07 in Curitiba, Brazil (LNCS Volume 5640, Springer, 2008), and GREC09 in La Rochelle, France (LNCS Volume 6020, Springer, 2010).

GREC2011 was organized in a single-track, two-day program of several sessions dedicated to specific topics. For each session, there was an overview talk (long presentation) that presented the state of the art and noted the open questions for the session's topic, followed by a number of short presentations that contributed by proposing solutions to some of the questions or by presenting results of the speaker's work. Authors gave short presentations, leaving time for panel discussions. Each session was concluded by a panel discussion. The role of the chairpersons was of key importance in this format. Session chairs were asked not just to introduce speakers, but to read papers before his session and to prepare a survey presentation on the topic with a list of questions to foster active discussions and encourage participation. With this purpose, electronic proceedings with full papers were available to registrants allowing electronic discussions before the workshop.

The scientific program consisted of 36 scientific presentations and three contests. It contained both classical and emerging topics of Graphics Recognition. Session topics included map and ancient documents, symbol and logo recognition, indexing and retrieval of data, sketch and drawings, feature extraction, challenge processing, and performance evaluation. Continuing with the tradition of past GREC workshops, the program of GREC2011 included graphics recognition contests. In particular, three contests were held: an arc segmentation contest organized by Abdullah Zawawi Talib, Hasan S. M. Al-Khaffaf, and Mohd Azam Osman, a symbol recognition contest organized by Ernest Valveny, Mathieu Delalandre, Bart Lamiroy, and Romain Raveaux, and a contest of music scores (writer identification and staff removal) organized by Alicia Fornes, Anjan Dutta, Albert Gordo, and Josep Llados. The results of contests will be reported to the post-proceedings LNCS book.

GREC2011 was successful, with 34 participants from  various academic institutions and research centers from 12 countries. Graphics Recognition is a dynamic, active, and promising scientific community.

The social program was appreciated as well. Participants had a great time socializing during the workshop and enjoying a world class performance of Nanta as well as the banquet. Finally, we wish to thank the sponsors, Suprema Inc and Triple Aims, for their generous support.

Next workshop will be held within two years in North America just before the ICDAR conference.
