Abstract: A method for processing images of seeds, the method comprising: inputting a seed image comprising at least a portion of a seed to a trained neural network to generate a value associated with the coverage of a coating on the seed; the trained neural network having been trained to generate a value associated with the coverage of coating on the seed using a plurality of training images each comprising at least a portion of a training seed, and wherein each training image is labelled with a value associated with the coverage of a coating on the training seed.
