Novel Approach in Modeling the Extents of Moving Objects

Recently many applications like fire simulation bring more interests in the extents of moving objects. Present research usually focuses on the positions of moving objects. The proposed models are more compatible for the position management. As a result, tracking the continuously changing extents of moving objects is becoming increasingly necessary. This paper proposes a novel model that can represent the irregularly changing shape of moving object. It also supports the querying of the predicated near future extents. The method is capable of representing objects evolving in two- and three-dimensional space. We also provide user-defined precision level to decide the quality of modeling. Our experimental results performed on stimulation datasets show that the model is effective for representing and querying the extents of moving objects.
