Classification system for yellow-skinned potatoes by color image analysis

Abstract

Potato appearance quality assessment, a highly subjective exercise, is today an important factor for the food market. Work undertaken by Cemagref in cooperation with ITPT has lead to the validation of an experimental classification method based on the potatoes appearance. This method based on two colour component analyses which performs a classification function related to tuber brightness and blemishes. The software developed in this project has allowed us to validate the method against human expertise, with a 80 % success rate.
