Unlike image data, video (animation) data contain the motion of objects. The spatiotemporal correlation of objects may represent certain semantic contents, which are not perceived by focusing only on the motion of an individual objects independently. We propose a content-based retrieval framework based on the spatiotemporal correlation of objects with a set of description factors of spatiotemporal relations of objects.
