In contrast, in the leaf dataset, there is less information due to the limited vision field that is focused on fewer leaves, but the edges and venation are observed with a better resolution than when the image is of the entire plant. The venation is part of the plant's vascular system, much like veins in humans and other animals. The arrangement of veins and veinlets on the lamina of a leaf is called venation. Venation Definition & Meaning - Merriam-Webster A principal function of the venation is to deliver water; however, a hydraulic significance has never been demonstrated for contrasting major venation architectures, including the most basic dichotomy, "pinnate" and "palmate" systems.
