retinalysis-vascx: An explainable software toolbox for the extraction of retinal vascular biomarkers
VascX is an open-source software toolbox designed to automatically extract explainable and flexible biomarkers from retinal artery-vein segmentations using color fundus images. It uses a four-stage pipeline—skeleton, undirected graph, directed digraph, and resolved vessels—to compute metrics like vascular density and tortuosity across different anatomical regions defined by the optic disc and fovea.
