Unsupervised Cardiac Image Segmentation via Multiswarm Active Contours with a Shape Prior

Table 3

Average similarity measure with the correlation, Jaccard and Dice indices, Hausdorff distance, and the maximum cardinality similarity metric among the ventricular areas segmented by the Graph Cut method, traditional ACM, interactive Tseng method, our proposed method, and the regions outlined by experts of the MR dataset.
