Abstract

A method of training a classifier for computer aided detection of digitized medical images, includes providing a plurality of bags, each bag containinga plurality of feature samples of a single region-of-interest in a medical image, wherein said features include texture, shape, intensity, and contrast of said region-of-interest, wherein each region-of-interest has been labeled as either malignant (11) or healthy (13), and training a classifier on said plurality of bags of feature samples, subject to the constraint that at least one point (12) in a convex hull (14) of each bag, corresponding to a feature sample, is correctly classified according to the labeled of the associated region-of-interest.
