Investigation on automatic change detection using pixel-changes and DSM-changes with ALOS-PRISM triplet images
A new algorithm for automatic change detection is presented. It detects a pixel-change and DSM-change from two orthoimages and two DSMs, then it extracts the polygons in elevation-changed areas. Pixel-change is detected by using least squares fitting technique. This method can extract the visible ch...
