  1. Two techniques are shown, the graph cut program described here, and a previously published level set technique. Four different methods are used to measure the difference between techniques. All measurements are given in terms on pixels on an image. DSC: Dice’s similarity coefficient, MSPE: mean unsigned surface positioning error, HD: Hausdorff distance.
