Quasi-tracklet fusion accounting for cross-correlation

Abstract

This paper deals with distributed fusion with local quasi-tracklets and provides the optimal linear minimum mean-squared error (LMMSE) fusion, namely optimal quasi-tracklet fusion. We analyze its performance, present a necessary and sufficient condition under which the fusion is identical with the centralized fusion, and exploit its relationships with some existing distributed fusion methods. Numerical results are provided to illustrate its performance compared with the centralized and existing distributed fusion algorithms.
