Hi, The 2 parameters have different effects. The spatial radius limits the pixels which will be used for the local mode computation during the filtering step before segmentation. The minimum region size is just a post-processing step.
So this is the theory ;). However, with segmentation, the best is to experiment a little bit with the parameters.
