The Effect of Window Size Changing on Satellite Image Segmentation Using 2D Fast Otsu Method	2017	12	.pdf	application/pdf	2282	102	72	The central gray level (GL) and local mean values are similar (as Al Razzazah image, take window size 5), and are near (as Al-Ramadi and Al Fit’ha images, take window size 5, 15, and 25) as shown in In order to determine the optimum threshold value (valley) a plot is drawn between the possible threshold values that is found using the (2D) histogram with the window size, where the flat area represent the optimum threshold value (valley) to separate the regions (classes).
