Modelling Moving Objects in Multimedia Databases
Mohammad Nabil, Anne H. H. Ngu, John A. Shepherd · 1997
In this paper we propose a new model for moving objects, aimed at handling video sequences in multimedia databases. The model integrates the representations of individual moving objects and the time-varying relationships between multiple moving objects in a scene. Several new query operators are defined within this model. Some examples illustrating the power of the model are provided.

Multimedia information contains complex objects that are composed of objects from different media such as text, graphics, images, audio and full-motion video. Multimedia objects may ha...
