Image analysis and characterization of cereal grains with a laser range finder and camera contour extractor

(...) Discriminant functions were established to discriminate between wheat and nonwheat with 99.5% accuracy and between nonwheat and wheat with 98.3% accuracy. The discrimination between two soft white and two club wheats was about 90% accurate. The discrimination between two- and six-rowed barley was about 90% accurate, between barley and other grains 97% accurate, and between rye, triticale, and other grains 90% accurate. Discrimination between wheat, soybeans, oats, wild oasts, dent corn, flint corn, wild buckwheat, sorghum, and lamb's-quarter was almost 100% accurate
