Detecting Maturity in Fresh <i>Lycium barbarum</i> L. Fruit Using Color Information
The accurate quantitative maturity detection of fresh <i>Lycium barbarum</i> L. (<i>L. barbarum</i>) fruit is the key to determine whether fruit are suitable for harvesting or not and can also be helpful to improve the quality of post-harvest processing. To achieve this goal,...

The accurate quantitative maturity detection of fresh <i>Lycium barbarum</i> L.

To achieve this goal, abnormal samples were eliminated by the Mahalanobis Distance (MD), and nine components (i.e., R, G, B, H, S, V, L, a, and b) of the ripe fruit, half-ripe fruit, and unripe fruit were extracted, firstly. Then, significant component combinations of the three fruits beneficial to the extraction of their areas were determined. Through binary processing, morphology processing, and other image processing methods, a quantitative maturity detection model of fruit was established based on the support vector machine (SVM) model.
