This paper addresses the problem of document production in the context of an electronic market application, namely a platform dealing with requests for proposals (RFP). Our project relies on XML as the leading technology, in accordance with a general trend in electronic commerce. The consequences of the RFP workflow on the document publishing requirements(More)
In the context of a new project around structured document recognition, we address the problem of designing a software architecture which is able to integrate all the necessary, but heterogeneous know-how. Starting from the new needs brought by the CIDRE project, we propose a concrete framework built upon existing software pieces, and following the(More)
Even if font usage plays an important role in Document Image Analysis (DIA), recognition systems generally take the concept of font management in a weaker sense than in the production cycle. With the point of view of the document recognition community, we show how typographic information (characters bitmap, metrics, etc.) can improve existing analysis(More)
The optical retrieval and storage technique called VisualAudio provides a way to extract sound information from an analog disk without any mechanical contact. The process is straightforward: we take a picture of each side of the disk using a dedicated analog camera, we store the film as our working copy, and when needed, we scan the film and process the(More)
Assisted document recognition systems have to integrate automatic recognition, manual edition and incremental learning in a single interactive environment. This paper raises the question of the organization of these three kinds of operations. When an analyzer has the ability to improve with use, there is a tradeoff between the benefits of enhancing the(More)
Historical sound documents are of high importance for our cultural heritage. The sound of phonographic records is usually extracted by a stylus following the groove, but many old records are in such bad shape that no mechanical contact is possible. The only way to read them is by a contactless reading system. A phonographic document analysis system was(More)
The sound of phonographic records is contained in the radial position of the groove (and sometimes also its depth). The sound is usually extracted by a mechanical device (the stylus of the record player). Many old records are in such bad shape that no mechanical contact is possible. An alternative is to take a picture of the record and to estimate the(More)
