TrainImagesClassifier processing parameter sample.bm cannot be changed
Processing parameter of TrainImagesClassifier "Bound sample number by minimum" (sample.bm) is always set to 1 which fits the number of samples to the smallest class. This is unfavourable for unbalanced datasets where information of frequent classes is lost. Changing the parameter to 0 does not have the expected effect that all samples are used.
