One segmentation approach is image clustering, which is a form of unsupervised classification that groups similar data (pixels) together by comparing the distance of each data point to different cluster centers.
Web1 jul. 2011 · The method suggested by Sean de is fine to normalize the maximum intensity. However, it will not necessarily give you the same appearance for both images (due to the intensity distributions not definitely being scaled by a multiplicative factor). I suggest you try the histogram transfer method in order to get a somewhat similar appearance.
