An Automatic Cognitive Graph-Based Segmentation for Detection of Blood Vessels in Retinal Images
Table 2
Graph-based segmentation performance without and with correction methods on DRIVE, ARIA, and STARE datasets, respectively. 2nd row: CLAHE () [3, 4, 41]. 3rd row: Retinex (, spatial spread based on low-pass filter , and geometric spread of the image intensity ) [5]. 4th row: subtraction median blurring image of green () from green image [6]. 5th row: subtraction low-pass Gaussian blurred image of green () from green image. Se: sensitivity, Sp: specificity, Acc: accuracy, and AUC: area under curve.
