Summarization of scalable multimedia documents

The summarization of a multimedia document is a challenge that requires the summarization of media elements combined into a document but also relies on an appropriate adaptation of its presentation. In this paper, we present a scalable multimedia model that structures the multimedia scene into incremental Spatial, Temporal and Interactive layers and progressively provides presentation details. Our proposal consists in summarizing such scalable multimedia documents based on three adaptation parameters: a targeted level of expertise, a preferred duration and a level of expectation for extended information. Our approach has been technically validated on PowerPoint-like documents using a generic MPEG-21-based adaptation framework.
