Abstract: A method of identifying NPK-deficiency includes measuring intensities of light reflected from a cannabis plant to produce intensities at a set of spectral bands, wherein the cannabis plant is one variety of a plurality of varieties of cannabis. The intensities are applied to a classifier so that the classifier provides one of an indication that the cannabis plant is NPK-deficient or an indication that the cannabis plant is NPK-sufficient, wherein the classifier has been trained using plants that include each of the plurality of varieties of cannabis.

Abstract: A method includes applying an image containing a plurality of wheat spikes to a trained neural network to produce a plurality of sub-images, each sub-image comprising a respective single wheat spike segmented from other wheat spikes of the plurality of wheat spikes. Each sub-image is applied to a second trained neural network to produce at least one disease pixel set, wherein each disease pixel set consists of pixels depicting a diseased portion of a wheat spike.
