A study of change detection from satellite images using joint intensity histogram
2008
Pattern Recognition (ICPR), Proceedings of the International Conference on
Detection of appearance/disappearance of objects from satellite images is generally very difficult since background pixels also change their intensity values owing to various factors. In this paper, we propose a method to estimate such background intensity changes by analyzing the joint intensity histogram of compared images. Considering the fact that background intensity changes tend to make clusters with ridges on the joint histogram, dominant ridges are detected using Hough transformation.
