Abstract
A produce grading system that detects the light reflectance from an object in four color bands. Two bands are in the visible range and two are in the invisible range. By comparing various color combinations the system looks for the presence of a desired color, an undesired color, and determines if the object is vegetable or nonvegetable matter.
