I’ve just tried the processing chain (refined Lee filtering => Supervised Wishart Classification Training => Supervised Wishart Classification) with RS2 full-pol data on my computer and have no problem. Here I used Refined Lee Filter in Polarimetric Speckle Filter and the output is in T3 matrix format. For Washart classification, the input should be in either the original full-pol format or in coherence matrix T3 format. But if I forget to specify the location of the “Training Data Set” file in the UI of the Supervised Wishart Classification operator, then I got the following error.
