Iron deficiency chlorosis classification. The Orthomosaic (top) is first classified into plant and soil pixels (bottom left). The plant pixels are then classified in a second step to green pixels (%G), yellow pixels (%Y), and brown pixels (%B) (bottom right). These features are then related back to ground-based visual scores through random forest and neural network models to classify tolerant and susceptible plots
