Dorota Duda, Marek Krętowski, Johanne Bézy-Wendling
2004 Lecture Notes in Computer Science  
A new approach to the hepatic primary tumor recognition from dynamic CT images is proposed.  ...  In the first step of the proposed method, texture features are extracted from manually traced ROI-s to objectively characterize lesions. The second step consists in applying decision tree classifier.  ...  In the paper texture-based classification of hepatic lesions from CT images is investigated.
