An efficient gyro-aided iterative Earth Mover's Distance (iEMD) algorithm for visual tracking is proposed in this paper. The Earth Mover's Distance (EMD) is used as the similarity measure to search the optimal template candidates in color-spatial space in a video sequence. The computation of the EMD is formulated as the transportation problem from linear(More)
One of the distinguishing characteristics of a data stream system is 'a continuous query operating on dynamic data' as opposed to 'static data processed by instantaneous query' in DBMS. In this paper, we propose a system of operators to process a continuous query on sliding windows over streaming data. We use the pre-defined notion of sliding windows over a(More)
