✦ Synopsis

Wheat grain quality assessment is important in meeting market requirements. The thickness of grains can be used for the measurement of the mass proportion of grains that pass through a sieve. This measure is known as ''screenings''. The determination of the presence or absence of the grain crease aids the detection of a stain called blackpoint, which is usually most evident on the non-crease side of the grain. In this paper we investigate the use of stereo vision techniques for measuring the thickness and detecting the presence or absence of the crease of a sample of wheat grains placed on a tray with dimples.
