1. Change detection in Hyperspectral data Dr. Prashanth Marpu (marpu@hi.is) Prof. Jon Atli Benediktsson University of Iceland, Reykjavik, Iceland Prof. Paolo Gamba University of Pavia, Pavia, Italy

4. Our approach Ongoing Work FR Time 1 Time 2 Initial change mask Change detection using IR-MAD method Post-processing Change map

10. Multispectral change detection using IR-MAD and initial change mask.

11. Experiments with ICM Landsat ETM+ images over Juelich, Germany taken in May, June and August, 2001. Major changes due to agricultural regions. Only the human settlement areas and mining area remain unchanged.

12. Experiments May- June May- August

13. Experiments Without Mask With Mask May -June

14. Experiments

15. Experiments Without Mask With Mask Automatic radiometric normalization

16. Experiments May- August Without Mask With Mask

17. Experiments Without Mask With Mask Automatic radiometric normalization

19. Effect of feature reduction in the multispectral case Comparison of the slopes for radiometric correction using manually selected no-change pixels and automatically selected no-change pixels using different inputs.
