Rapid Assessment of Earthquake-Induced Building Damage Using Optical Image Correlation

Rapid assessment of earthquake-damaged building-such as area, quantity, and severity-is crucial for timely post-earthquake rescue. Pre- and post-earthquake data collected from optical remote sensing systems can effectively resolve earthquake deformation. Among them, the normalized correlation coefficient reduction (NCCR) shows promise in directly reflecting building damage. Here we propose an automated processing chain for building damage detection, which integrates subpixel image correlation te
