Change detection: (a) sample background, (b) sample foreground, (c) 1D scan from background, (d) 1D scan from foreground, (e) the subtraction of foreground and background scan, (f) the subtraction of two scans after outlier removal step, (g) result of clustering to find changes in the foreground scan, (h) corresponding changes on point cloud, (i) frequency of the scan, and (j) result of change detection.
