Building detection with spatial voting and morphology based segmentation
2016 24th Signal Processing and Communication Application …, 2016•ieeexplore.ieee.org
Automated object detection in remotely sensed data has gained wide application areas due
to increased sensor resolution. In this study, we propose a novel building detection method
using high resolution DSM data and true orthophoto image. In the proposed method, DSM
feature points and NDVI are obtained. Then, they are used for spatial voting to generate a
building probability map. Local maxima of this map are used as seed points for
segmentation. For this purpose, a morphology based segmentation method is proposed …

Then, they are used for spatial voting to generate a building probability map. Local maxima of this map are used as seed points for segmentation. For this purpose, a morphology based segmentation method is proposed. This way, buildings are detected from DSM data. We tested our method on ISPRS semantic labeling dataset and obtained promising results.
