Algorithm for Mango Classification Using Image Processing and Naive Bayes Classifier

Mangoes are one of the most preferred fruits in the world, and one of the most crucial to the economy of the Thai fruit industry. The Thai government has therefore set a policy to encourage mango growers to improve the quality of their mango fruits. Mango fruit inspection is important for the quality control system of mango fruit production. This paper presents a Bayesian approach for mango classification based on digital image processing. The algorithm is designed to identify a defect on the mango skin and classify it into one of two groups: ‘unripe mango’ or ‘ripe mango’. To determine the defect on the mango skin, image thresholding and image labeling are applied. Colour features are extracted from RGB mango images using statistical calculations. The naive Bayes classifier is then applied to classify the colour-based feature of the mango images. The performance of the Bayesian approach was evaluated against another classification technique-the Support Vector Machine (SVM). The method was implemented and tested on 100 mango images. The surface defect detection achieved 85% accuracy. The experimental results show the superiority of the proposed method, with an accuracy of 90%, as compared to SVM-based methods, with an accuracy of 83%.
