I am trying to classify SPOT images with the support vector machine classification in Orfeo Toolbox with QGIS. I installed Orfeo Toolbox with OSGeo4W. I have made a ROI image with 600 training samples (2 classes), and used TrainImagesClassifier (svm). However when I use Image Classification to classify the image with the svm, it gives me an error. The log only says:
the following layers were not correctly generated: Output image, Confidence map
I have tried using different images, leaving it to save to temporary file, and changing the save directory but nothing works.
