 We also applied the 2% image stretching to provide a fast visualization with high contrast. With the image on the screen, we selected the Image Segmentation method to produce regions according. We have selected the minimum number of pixels as 25 to avoid very small regions, and defined a similarity threshold of 0.01, based on the minimum euclidean distance of pixels with 4 bands to be considered homogeneous. We also applied the 2% image stretching to provide a fast visualization with high contrast.
