The United States Standards for Sorghum, maintained by the USDA Agricultural Marketing Service (7 CFR §§ 810.1401-810.1405), define grade factors including test weight, damaged kernels, broken kernels, and foreign material. Vibe imaging workflows measure the same morphology and defect parameters these grades depend on.
