Ten Years of Research in the Analysis of Graphics Documents: Achievements and Open Problems

Colloque sur invitation.Our research group has been investigating various aspects of graphics recognition techniques for more than ten years. We have worked on map analysis, symbol recognition, dimension analysis and the conversion of engineering drawings to CAD models. Lately, we are also conducting research on the interpretation of architectural drawings. In addition, we have built up a software platform of generic tool for graphics document image analysis, and we have participated in many international activities around the topic of graphics recognition. In this paper, we present some of our achievements and results from these ten years, and we propose a number of open problems, which we think are good challenges in the coming years, for ourselves and for other teams

Graphics Recognition: The Last Ten years and the Next Ten Years

GREC'05 marked the 10th anniversary of the series of international workshops on graphics recognition, for which the first edition was held in Penn State in 1995. At the end of the workshop, a panel discussion was held to take a broader view of our field, to examine the shift in issues addressed by research teams, and define some challenges for the coming years. This paper tries to summarize the results of the panel discussion

Is Graphics Recognition an Unidentified Scientific Object?

International audienceThis paper summarizes the presentation and discussions at the panel session held at the conclusion of the GREC'07 workshop. After making a short review of where the graphics recognition stands, we raise some questions (hopefully) of interest for the future of this community

Analysis of Engineering Drawings: State of the Art and Challenges

Contribution à un ouvrage.In this paper, we analyze the state of the art in interpretation of engineering drawings, both from a methodological point of view and from the perspective of the applications. We try to emphasize where techniques are mature, where they need further maturing, and where we still have open challenges. Special attention is given to the progress in the last two years

Graphics Recognition -- from Re-engineering to Retrieval

Invited talk. Colloque avec actes et comité de lecture. internationale.International audienceIn this paper, we discuss how the focus in document analysis, generally speaking, and in graphics recognition more specifically, has moved from re-engineering problems to indexing and information retrieval. After a review of ongoing work on these topics, we propose some challenges for the years to come

Handbook of Document Image Processing and Recognition

International audienceThe Handbook of Document Image Processing and Recognition provides a consistent, comprehensive resource on the available methods and techniques in document image processing and recognition. It includes unified comparison and contrast analysis of algorithms in standard table formats. Thus, it educates the reader in order to help them to make informed decisions on their particular problems. The handbook is divided into several parts. Each part starts with an introduction written by the two editors. These introductions set the general framework for the main topic of each part and introduces the contribution of each chapter within the framework. The introductions are followed by several chapters written by established experts of the field. Each chapter provides the reader with a clear overview of the topic and of the state of the art in techniques used (including elements of comparison between them). Each chapter is structured in the same way: It starts with an introductory text, concludes with a summary of the main points addressed in the chapter and ends with a comprehensive list of references. Whenever appropriate, the authors include specific sections describing and pointing to consolidated software and/or reference datasets. Numerous cross-references between the chapters ensure this is a truly integrated work, without unnecessary duplications and overlaps between chapters. This reference work is intended for the use by a wide audience of readers from around the world such as graduate students, researchers, librarians, lecturers, professionals, and many other people

A Few Steps Towards On-the-Fly Symbol Recognition with Relevance Feedback

http://www.springerlink.com/This paper presents some first steps in building an interactive system which allows a user to efficiently browse a large set of scanned documents, without prior knowledge on the content of these documents, and retrieving symbols of interest to him personally, through a relevance feedback mechanism

Musings on Symbol Recognition

This paper does not pretend to be yet another survey on symbol recognition methods. It will rather try to take a step back, look at the main efforts done in that area throughout the years and propose some interesting directions to investigate

Principes et mise en oeuvre de l'interopérabilité dans le système d'analyse de documents Qgar

Colloque avec actes et comité de lecture. Internationale.International audienceCet article décrit d'abord brièvement la plateforme logicielle d'analyse de documents Qgar, son architecture, ses grandes composantes, ainsi que les choix techniques retenus pour les outils et les formats utilisés. Il décrit ensuite plus précisément la solution mise en oeuvre pour faciliter l'interopérabilité au sein de la plate-forme, c'est-à-dire l'intégration des applications réalisées avec les briques logicielles fournies par la bibliothèque du système et l'intégration des applications importées. Chaque application est associée à un document XML qui fournit ses caractéristiques : description à l'usage des clients, types et valeurs des paramètres. Bien que simple et pragmatique, cette solution se révèle performante, pour exporter des applications Qgar ou pour importer des applications tierces, comme le montrent les exemples donnés
