TEXMEX Research Team
Efficient Exploitation of Multimedia Documents
Exploration, Indexing, Navigation, and Access to Very Large Databases

Presentation of the team

The explosion of the quantity numerical documents multimedia generated a very strong dynamism in the field of the multimedia indexing research. However, the range of the work undertaken by the media specialists is limited by their monomedia aspect and the quantity of the documents they can handle, a few thousands of images for example, whereas the professional applications wouold require to handle much more (a few million).

Such quantities of documents set difficult problems of structuring and storage on disc, problems which are out of the expertise of the media specialists. On the other hand, database specialists who are used this kind of the problems, consider only very rudimentary techniques of document description, by lack of know-how in this field.

To remedy that, we propose the creation of a team bringing together at the same time specialists of the media and specialists of the techniques necessary to use these documents such as data bases, information retrieval or statistics. The objective of the team is thus to be at the intersection of the two following axes :

The originality of our approach comes from the simultaneous consideration of the contraints dependent on the media and the documents and of the constraints related to the exploitation of these data, wich are two aspects of the same problem. This multi-field approach must make it possible to exced the limits of the current systems and to manage finely and effectvely very significant quantities of documents.

Key words : exploration, indexing and research by content, big data bases, multimedia.

Research Directions

Our work is organized in two axes of work hich we apply to the study of three problems.
The axes of work are :

We apply these tools to three problems :

  1. The search for images in great bases of images ;
  2. The joint descriptionj text - image of documents comprising these two media ;
  3. The addition of semantic capacities to the textual search engines.
