The purity of product from agricultural cleaners (such as chile, cotton, bean, wheat and other crop cleaners) is needed to be measured under various conditions in order to adjust and optimize the machine at the design and improvement stages. The traditional weight-based method of measuring purity is time consuming, and requires much labor. This book uses image analysis to measure percent crop cover for the product output to infer the purity. Chile cleaner was used as one example machine. Photoshop© and Arcview© software were compared. The data collection process is more reproducible and less labor and time consuming than the traditional technique. (Imprint: Nova)
