Fruit Maturity Estimation based on Color Scales

Abstract

Color is an important parameter used to estimate fruit maturity and optimal harvest time. In this paper a general methodology for estimating fruit maturity based on the development of a color scale is proposed. Maturity estimation is performed by computing of the fruit representative color and its comparison with the colors of the scale. In experimentation the case of grape maturity estimation based on seed color is presented. The method is simple and eff ective, allowing its application in the real processes.
