Abstract(in English) | We report on a classification method for tumor segments in CT images of livers based on decision rules derived by inductive learning techniques. We also describe a method to classify types of segments based on time-trasition of CT values of segments obtained by Dynamic CT and Simple CT images. We define features of each segment or a group of segments based on morphological features which are typically used to discriminate cancers. We generate rules for discriminating cancer tumors from other ones are generated by applying decision tree analysis and score segments based on these rules. We further apply discrimination analysis to scores and original feature values to determine weight of each value for discriminating cancer segments. Experimental results of ROC analysis show that classification methods incorporating rules derived by inductive learning outperforms the one without learned rules in terms of generalization ability. |
