Modeling Multimedia Indexing Algorithms Description for Implicit and Explicit Indexation

The increasing amount of multimedia data is generally indexed by algorithms which extract metadata that will be further queried by users for retrieving some desired information. Because of the heterogeneity and the diversity of these indexing algorithms, it is not suitable to execute at once all indexing algorithms. Actually, it will overload the information system and will also produce metadata that may not be used inside the system. For example, in a car park surveillance system, it is not necessary to apply to all the video sequences algorithms that detect persons. However, at a certain time someone might want to know about the persons that crossed the parking.
