Modeling of moving objects in a video database

In this paper we introduce an innovative way to represent the trajectory of a single moving object and the relative spatio-temporal relations between multiple moving objects. The representation supports a rich set of spatial topological and directional relations. It also supports both quantitative and qualitative user queries about moving objects. Algorithms for matching trajectories and spatio-temporal relations of moving objects are designed to facilitate query processing. These algorithms cart handle both exact and similarity matches. We also discuss the integration of our moving abject model based oil a video model in an object-oriented system.
