Classifying the ripeness of mangoes using image processing and deep learning

Mango is a popular fruit that comes in many different varieties. Each variety has a different flavor, aroma, and texture. Selecting mangoes at the appropriate level of ripeness is therefore important to both consumers and producers. Problems frequently encountered include inconsistencies in sorting mangoes using traditional methods, which often rely on human experience and eyesight. This can affect the quality of mango product. This research focuses on developing a ripeness-rawness screening system for Okrong and Mahachanok mango varieties using Deep Learning and Image Processing techniques. Two CNN (Convolutional Neural Network) models, VGG16, MobileNetV2, and CNN1D, were used to analyze mango images and distinguish between ripe and raw levels. The test results showed that the VGG16 model achieved the highest performance in screening ripeness-rawness of both mango varieties, with an accuracy of 98%, followed by MobileNetV2 at 96% and CNN1D at 92%. For the ripeness-rawness classification of only the Okrong mango variety, the VGG16 model still achieved the highest performance, with an accuracy of 99%, followed by MobileNetV2 at 96% and CNN1D at 95%. These results indicate that CNN models, particularly VGG16, have great potential for application in developing automated mango sorting system based on ripeness-rawness levels. This proposed work can significantly improve efficiency in managing and selecting mango product.
