Results from the implementation of an online color imaging system on industrial snack food
production lines are presented. Feature information is extracted from images using multivariate
image analysis based on principal component analysis and is used to develop models to predict
the coating content and the coating distribution on the products. The imaging system is used to
monitor these product quality variables and to detect and diagnose operational problems in the
plants. It is also used to directly implement closed-loop feedback control over the coating
concentration.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
