An Improved Fuzzy Connectedness Method for Automatic Three-Dimensional Liver Vessel Segmentation in CT Images

Figure 11

Comparison of the improved fuzzy connectedness (with one single seed) with traditional fuzzy connectedness, region growing, and threshold level set (with multiple potential seeds). (a) and (b) show the accuracy, sensitivity, specificity, and Dice coefficient for the 3Dircadb and Sliver07 datasets, respectively. ACC = accuracy; SEN = sensitivity; SPE = specificity; DICE = Dice coefficient; IFC = improved fuzzy connectedness; FC = fuzzy connectedness; RG = region growing; LS = threshold level set.
