Automatic Image Segmentation Using Active Contours with Univariate Marginal Distribution

Table 2

Average similarity measure with the Jaccard and Dice indices among the ventricular areas segmented by the traditional ACM, interactive Tseng method, our proposed method, and the regions outlined by experts of the MR dataset.

Comparative studies	Similarity measure
	Jaccard index (J)	Dice index (D)
ACM versus experts	0.6666	0.8000
Tseng versus experts	0.7857	0.8800
Our method versus experts	0.9230	0.9600
