Multiple Active Contours Driven by Particle Swarm Optimization for Cardiac Medical Image Segmentation

Table 2

Average similarity measure with the Jaccard index, the Dice index, and the Hausdorff distance among the regions segmented by the traditional ACM, graph cut method, our proposed method (MACPSO), and the regions outlined by two experts of the set of MR images.
