“A good value is half the spatial radius used in the MeanShiftSmoothing application (spatialr parameter).”
in both Spatial and Range radii.
Segmentation — Orfeo ToolBox 7.3.0 documentation, which combines MS and LSMS, only asks for one pair of radii:
-filter.meanshift.spatialr int Default value: 5
Spatial radius of the neighborhood.
-filter.meanshift.ranger float Default value: 15
Range radius defining the radius (expressed in radiometry unit) in the multispectral space.
Should the user understand that the provided values (5 and 15 in the example) are repeated in both steps or is the aforementioned “good value” silently applied in the 2nd step?
