Figure 4: Example partitioning of the surveillance area based on a target density distribution. The target density distribution is represented by contour lines. The boundaries of the partitions are represented by thick, straight lines. The space of this plot represents the surveillance area over which the target density distribution is defined. The particular choice of partitions displayed is of little significance. What is significant is to note that the partitions are determined based on the information content provided by the target density distribution.
