From: Building detection from urban SAR image using building characteristics and contextual information
Detection results on test site I: (a) initial SAR image; (b) internal marker image; (c) external marker image; (d) edge strength map; (e) edge strength map with markers superimposing on it; (f) result of the watershed algorithm; (g) merged objects after removing small regions; (h) remained object after DCA; (i) external marker image obtained by our previous method; (j) segmentation result of our previous method; (k) building boundaries obtained after postprocessing of (j); (l) initial SAR image with reference building boundaries.
