Multiple photomicrographs of representative fields were examined to quantitate vessel types as described below.
Covassin, L. D., Villefranc, J. A., Kacergis, M. C., Weinstein, B. M. & Lawson, N. D. Distinct genetic interactions between multiple Vegf receptors are required for development of different blood vessel types in zebrafish.
Thus, through vessel diameter and flow velocity, different vessel types could be identified (Fig. 2a d).
Another distinguishing hallmark of different vessel types is their different blood flow velocities.
Different vessel types; arterioles, capillaries, venules, are known to respond differently to various stimuli7,9,11.
Blood flow velocity is an important tool for distinguishing vessel types.
Furthermore, some vessel types and their position within the vascular network may have higher hematocrits.

These three different classifiers focus on discriminating vessel types, vessel IMO numbers (classifying individual vessels on IMO training set), and both vessel types and IMO numbers (jointly classifying type and IMO numbers of vessels on IMO training set), respectively.
Among the 3965 vessels in IMO test set, there exist 29 vessel types that have at least 10 unique vessels, and each unique vessel has 50 example images.
