An Object-Based Change Detection Approach Using Uncertainty Analysis for VHR Images

Figure 5

Results of experiments of SPOT 5 images: (a) pixel-wise change map using SVM; semifinished change maps generated by uncertainty analysis under segment scale value of (b) 8, (c) 10, and (d) 12, respectively, where white regions are uncertain objects. (e) The final change map under the threshold value 0.8.
