*step 7- *otbgui_OGRLayerClassifier that takes as input the previous
shapefile and the image statistics and add a new "predicted"
attributes in the shapefile.
pb7.1 : The OGRLayerClassifier only seem to accept SVM models. It
worked for a SVM classifier but failed for a Random Forest with error
messages related to itk SVM .... need to develop an otbapp
I am just getting back to that thread, with a lot of activity and
comments. I just wanted to stress that pb7.1 is fixed in OTB 6.0 : you
know have access to all learning algorithm (including the unsupervised
shark K-Means we introduced in 6.0) in the TrainVectorClassifier app.
One step at a time ... There might also be in a near future a remote
module that allows to fix pb2.1.
Given all the insightful comments here, I think we could plan a working
group on this OBIA topic during next user days, to sum up what has been
said in the thread, add more ideas and write a good RFC to capture all
that. Then we could put it into action.
Thanks a lot for all your comments,
