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)
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)
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)
