Is the Otsu Thresholding or a manual thresholding implemented inside Sentinel-1 Toolbox (for radiometrically calibrated products)?
I know that a thresholding is included inside the Change Detection and the Oil Spill Detection/Clustering operators, but I’m wondering if there is a Thresholding function that can be used on its own?
Are you looking to implement your own and you’re looking for examples? If so, you can find some in the ship detection adaptive-thresholding and oil-spill clustering and change-detection operators.
If you want to use operators for general purpose thresholding look at creating expressions with Band Maths.
