Algorithm for measuring persimmon leaf layer thickness. (a) Leaf-scanning position with an optical scanner and 2D cross-sectional image of a persimmon leaf with different layers. (b) 2D cross-sectional image after flattening. (c) The depth profile of a region of interest (ROI) of a single leaf. (d) Depth profiles of four ROIs of a single leaf. (e) Average depth profile of four ROIs of a single leaf. (f) Curve-fitted depth profile of four ROIs of a single leaf. UE: upper epidermis, PP: palisade parenchyma, SP: spongy parenchyma.
