Image annotation specification for semantic components of lettuce leaves. A Images of lettuce leaves captured in an actual experimental environment. B The delineated leaf as four semantic components (BD blade, MR mid-rid, VS veins, and LM lamina). C Two new semantic components (VV venation and MZ marginal zone) automatically generated based on the corresponding semantic components. D Data annotation specification of six semantic components
