| Outline of Final Research Achievements |
Building damage detection technique is developed by utilizing non-linear mapping-based geometric correction, radiometric correction by histogram equalization, and change detection from image texture analysis. Building damage estimation model is developed integrated from seismic intensity and the proposed image texture feature using the aerial photographs, building damage data and seismic intensity data observed in the 2016 Kumamoto earthquake.
