Figure 4

Fixed and Mean thresholding effects on OCTA images skeletonization. SCP and DCP OCTA reconstructions are respectively shown in left and right images. Two detailed magnifications are taken in temporal and nasal sectors (orange squares). Since the step preceding skeletonization is image binarization, both for SCP and DCP plexa, it is possible to observe also in this case an underestimation of retinal capillaries, provided by Mean threshold (green square) compared to Fixed threshold (blue square).
