According to USDA standard guidelines, US grade 1 canola should have not more than 3% of total damaged seeds (distinctly green seeds and heat treated seeds). Distinctly green seeds should not be more than 2% and heat treated seeds should not be more than 0.1% . Graders usually identify these seeds by crushing a sample of canola and inspecting the crushed seeds visually. But visual inspection can introduce human error. Therefore, there is a need to develop an automated system that can distinguish these seeds from the desired canola seeds. Machine vision can be a potential method to achieve this objective as similar technology has also been applied on wheat and soybean to classify damaged seeds.
