The paper discusses three IST projects focusing on the disclosure of video content via a combination of low-level multimodal feature analysis, content abstraction, and browsing tools. The type of content (recordings of conference lectures and meetings) can be characterized as non-scripted and is argued to generate a whole range of new research issues. Performance results are reported for some o...

The amount of digital video and associated metadata being generated and stored is increasing rapidly. Given the complex spatial and temporal structure of video information it is a formidable challenge to provide compact and human-readable representations of such content. The solution has to be versatile in order to satisfy different user needs, such as browsing, zooming (looking for something s...

The usefulness of vast repositories of digital information is limited by the effectiveness of the access methods, as shown by the Web explosion. The key issues in addressing the access methods are those of content description and of information space navigati...
