Figure 4

The optimal parameter setting. (a) Dice coefficient vs. mask #m (m = 2, 3, and 4) for different number of clusters (c = 5–15) are presented in this figure. (b) Iteration number vs. termination threshold. Different FCM thresholding values were utilized to find an optimal rough mask and an optimal termination threshold of 0.02 was selected based on the accuracy and computation time.
