Performance of point similarity measure in multitemporal satellite images

In this paper, the performance of point similarity measure in multitemporal data of satellite images will be presented. Mutual information will be used as a measure of similarity. Therefore, every pixel will be assigned to its own value of mutual information. These pixels are then grouped into four...
