I find the module ObjectRadiometricStatistics very useful for vector classification. But we cannot use it through QGIS. I have already written an XML file for this module with OTB 6.4.0 and in QGIS 2.18. And this algorithm works properly. But with QGIS 3.4 and as OTB is become an external plugin, I don’t know where and how to put the XML file so that the module appears in QGIS processing toolbox.
Any help or suggestion would be useful.
