Image processing of conjunctival vasculature and fractal analysis. Conjunctival vessels were segmented by using custom software to extract the conjunctival vessels for fractal analysis. The raw image was resized to 1024 × 683 pixels (a). Segmented vessels after using adaptive histogram equalization and morphological opening operations (b). Cropped image of 512 × 512 pixels with a field of view 7.87 × 7.87 mm2 (c). Skeletonized vessel image (d). Fractal analysis of the skeletonized image (e). Bars = 3 mm
