Abstract: We examine the problem of indexing objects in animated movies. We consider an animated movie as consisting of a frame sequence where each frame is described by objects in a 2-dimensional space. The queries of interest are of the form: \ nd the objects that were in area S between frames f i and f j ". The straightforward approach to index such objects is to consider the frame sequence as another dimension and use a 3-dimensional access method (like an R-tree) to index all objects. Instead we...

...or change their extent over time. Recent works that address indexing problems in a spatiotemporal environment include [36, 15, 14, 28, 38, 3, 24, 25, 16, 32, 36]. Two variations of the problem are examined: approaches that optimize queries about the future positions of...
