1. A method for classifying regions of interest within a medical image, comprising the steps of:

  • training a classifier on a set of medical image training data, which training data includes segmented regions where a clinical ground truth classifying the segmented regions is known;

    acquiring non-training medical image data for investigation;

    generating an initial segmentation for a region of interest of the medical image;

    generating a plurality of candidate segmentations based on the initial segmentation;

    comparing the initial and the plurality of candidate segmentations with each other;

    selecting a best segmentation from a set of segmentations including the initial and the plurality of candidate segmentations based on the comparisons, where the selected best segmentation is used to train the classifier;

    processing the segmented regions to extract a full feature set for each of the segmented regions; and

    classifying the regions of interest using the full feature set;

    wherein, the step of training includes using a recommender to realize a stable segmentation.
