Fig. 2.

Representative example of a mean image (a) and context-aware contrasted mean image (b) generated from a stabilized HVM image sequence. Algorithmically recognized vessel structures are visualized in c, while superimposition of the detected vessel structures onto the mean image demonstrate short segments of false-negative (d, black arrows) and false-positive (d, white arrows) vessel recognition. Recognized capillary and venular centerlines are marked as black and dark gray lines (c) or dashed lines (d), outer vessel delineations are marked as light gray lines
