the effect of them on the features to be extracted
and used for classification. Among the features, there were significant differences between maturity
stages for mean values of R, G, b*, gray scale and S channels. Two classifiers based on linear (LDA) and
quadratic discriminant analysis (QDA) were used to assess the applicability of vision system. The results
showed that QDA classifier could be valuable in categorizing the fruits with better overall accuracy rate
of 90.24%.
