INVENIO: An MPEG-7 image indexing platform for content re-use within audio-visual production chains

In this paper, we propose a novel image indexing platform, so-called INVENIO (INdexing Visual ENvironment for multimedia Items and Objects). Entirely based on the ISO/MPEG-7 normative specification, the INVENIO platform offers, within an integrated system, visual metadata extraction engine, annotation tools, image databases management tools, as well as appropriated, ergonomic user interfaces. In order to validate the INVENIO platform, we have considered an industrial application related to the issue of content re-use within an audio-visual production chain, including both natural and synthetic (i.e. cartoons) image content. The proposed solutions demonstrated that the exploitation of the MPEG-7 visual descriptors makes it possible to obtain significant savings in terms of production time/cost, while ensuring an optimal re-use of content. The INVENIO platform has been validated within the framework of the HD3D-IIO structural project of the French CapDigital competitiveness cluster.
