An optical radiation measurement system, which measures reflectance spectra from 400 to 2000 nm, was usedto quantify single wheat kernel color. Six classes of wheat were used for this study. A neural network (NN) using inputdata dimension reduction by divergence feature selection and by principal component analysis was used to determinesingle wheat kernel color class. The highest classification accuracy was 98.8% when the divergence feature selectionmethod was used to reduce the number of NN inputs. The highest classification accuracy was 98% when principalcomponent analysis method was used to reduce the number of NN inputs.
