PRIAM Médiaworks Project

Keywords : TV archives , video databases .

Participant : Patrick Gros.

This is a joint project with the VISTA team of IRISA. Duration 46 months, Start date: September 2000. Partners: LIMSI - CNRS, AEGIS, INRIA (VISTA, TEXMEX, and IMEDIA projects), TF1.

The Mediaworks project was created in the frame of the PRIAM program and the French information society program, financed by the Ministry of industry. It began on September 1st 2000. This project gathers the TF1 TV channel, the LIMSI lab, AEGIS (a SME) and INRIA (projects IMEDIA of the INRIA Rocquencourt and VISTA). It concerns the development of a system to assist documentalists who index TV archives. Its principal features are the cooperation between the text and image media, and the development of a semantic search engine. TEXMEX works together with VISTA to develop tools for automatic structuring of video in plans and for computing an iconic representation of these plans.

RNRT Diphonet Project: Photo Diffusion on Internet

Keywords : copyright protection , image databases , image recognition , piracy .

Participants : Laurent Amsaleg, Patrick Gros, Sophie Le Delliou.

Duration : 30 months, starting January 2002. Partners: Canon, L2S, Andia Presse, INRIA (projects CODES, TEMICS and TEXMEX).

Copyright protection is a key component to allow photo holders like photo agencies to diffuse their collections through the Web. It seems today impossible to avoid skilled hackers to thrust their way in Web sites and rob images. Therefore, legal image holders need a way to check whether the images available on a third party site do not originate from their own database (DB) of images. This is particularly crucial if that third party is making money by selling the images it pretends to possess. Watermarking is a first solution to this problem, but it requires a complex organization to become a legal argument. Moreover, pirated images are often washed out in order to remove the inserted marks.

This project addresses the problem enforcing the protection of copyright by relying on a content-based image retrieval (CBIR) scheme for that. The idea is provide a tool allowing professionals (e.g. photo agencies) to check if a published image comes from their DBs using only visual similarity. Its goal is therefore to detect matches between a set of doubtful images (e.g. downloaded from the Web) and the ones stored in the DB of the legal holders of photographies. If an image was indeed stolen and used to create a pirated copy, it tries to identify from which original image the pirated copy comes from.

So far, we performed extensive experiments showing that our image description scheme was useful in this context.

RIAM Annapurna Project

Keywords : Personal photo archives , image indexing .

Participants : Patrick Gros, David Bonnaud.

Duration 12 months, Start date: January 2003. Partners: Thomson, LTU, CLIPS-IMAG.

The ANAPURNA project is a small project focused on demonstrating the feasibility of a management system of pictures on a digital set-top box in a familial context of use. The projects concerns the definition of the possible ergonomy of such a system, and brings together three technologies: image description, image indexing and search, and tuning of the system on an experimental platform developed by Thomson.

TEXMEX was in charge of the indexing and retrieval part of the project, which allowed to transfer to Thomson the results of Sid-Ahmed Berrani's thesis.


Keywords : TV archives , video databases .

Participants : Patrick Gros, Christophe Garcia, Manolis Delakis.

Duration 24 months, Start date: october 2003. Partners: Communications et Systèmes, INA, IRIT, Canal+ Technologie, Vecsys, Arte France.

The FERIA project aims at developing a framework for the development of multimedia applications in the domain of archive diffusion and valorization. This framework should allow to develop easily applications in the domain of multimedia production. These applications, in a second stage, will be used to produces DVD, web sites or other products.

Within this project, TEXMEX is in charge of still image analysis (logo and text detection, face detection and recognition), and of coordinating a research group on multimedia description of video documents.
