Comparative Study of Retinal Vessel Segmentation Based on Global Thresholding Techniques

Figure 10

Measures of CLAHE combined with different filters using ISODATA threshold. It describes the average sensitivity, specificity, and accuracy of the segmentation results obtained through CLAHE with ISODATA thresholding using different filters. CLAHE with guassian filters, combined with (ATC), gives the best performance of an average accuracy of 0.94997, average sensitivity of 0.67011, and average specificity of 0.97695.
