From: Building detection from urban SAR image using building characteristics and contextual information
Detection results on test site II: (a) initial SAR image; (b) edge strength map with markers superimposing on it; (c) results of the watershed algorithm; (d) building boundaries obtained by the proposed method; (e) edge strength map with markers superimposing on it, where external markers are extracted according to our previous method; (f) watershed segmentation result based on (e); (g) building boundaries obtained on (f) after postprocessing; (h) initial SAR image with reference building boundaries.
