Abstract

In this paper, we propose a new spatio-temporal representation scheme which can model moving objects' trajectories effectively in video data and a new signature-based access method for moving objects' trajectories which can support efficient retrieval on user query based on moving objects' trajectories. The proposed spatio-temporal representation scheme supports content-based retrieval based on moving objects' trajectories and concept-based retrieval based on concepts(semantics) which are acquired through the location information of moving object's trajectories. Also, compared with the sequential search, our signature-based access method can improve retrieval performance by reducing a large number of disk accesses because it access disk using only retrieved candidate signatures after it first scans all signatures and performs filtering before accessing the data file. Finally, we show the experimental results that proposed scheme is superior to the Li and Shan's scheme in terns of both retrieval effectiveness and efficiency.
