Table 3.
Comparison of average number of strokes and total time (seconds) required to achieve a pre-set Dice accuracy for different interactive segmentation methods. “-” denotes that no matter how many strokes are drawn, the pre-set dice cannot be achieved. Note that for the proposed method, in the first round, we often use two strokes for each of the three anatomical views. Therefore, for the proposed method, the first round has already consumed six strokes. “S” and “T” represent the strokes and total time, respectively
