I made this tutorial. I used Landsat 8 bands (1-7), which I atmospheric corrected with DOS and converted to 8-bit. After that I layer stacked the pre processed band (1-7), clipped a little part with a polygon shape of the whole image and used it as input for "Exact Large-Scale Mean Shift segmentation step 1".
But after step 4 I just get a very bad segmented shapefile. The tool just segmented a little percentage of the objects in my Landsat 8 clip. Anyone has a idea how to fix this?
