| Abstract: | According to the regional characteristics of buildings in high-resolution,remote sensing images,we apply Multi-threshold Segmentation,Category Selection and Mathematical Morphology Operator to the post-processing of the Difference Method.Then we propose the region-based difference segmentation extraction in extraction of earthquake damage and intact buildings.We extract the earthquake damage and intact buildings in a block in Dujiangyan City hit by the 2008 Wenchuan earthuqake in Sichuan Province,we compare... |
| Keywords: | assessment of earthquake damage variation detection region-based difference segmentation mathematical morphology operator |
