A computer-based image analysis system was developed for the automatic classification of brain tumours according to their degree of malignancy using Support Vector Machines (SVMs). Morphological and textural nuclear features were quantified to encode tumour malignancy. 46 cases were used to construct the SVM classifier. Best vector was obtained performing an exhaustive search procedure in feature space. SVM classifier gave 84.8% accuracy using the leave-one-out method. To validate the systems' generalization to unseen data, 41 cases collected from a different hospital were utilized. For the validation unseen data set classification performance was 82.9%. The generalization ability of the proposed classification methodology was verified enforcing the belief that automatic characterization of brain tumours might be feasible in every day clinical routine.
