Comparative Study of Retinal Vessel Segmentation Based on Global Thresholding Techniques

Figure 8

Measures the different phase congruence-based global thresholding approaches. It describes the average sensitivity, specificity, and accuracy of the segmentation results obtained through phase congruence using different global-based thresholding techniques. Phase congruence with IDM-based threshold, combined with (MO), gives the average accuracy of 0.94302, average sensitivity of 0.71520, and average specificity of 0.96496.
