Apple Internal Quality Classification Using X-ray and SVM

Classify the apple’s internal quality is important for apple’s quality. Mould core apple is not eatable and can reduce the juice quality if used for making juice. The core tissue’s color is brown and the density of mould core apple is lower than a normal apple. This paper describes the detection of apple’s one internal quality (mould core disease) on the physical basis -density. X-ray technology can provide us internal image of an object that reflects the object’s density. This paper presents the method of processing the X-ray image and creating the feature vector for using support vector machine (SVM) method to classify the apple’s internal quality. The experiment results show that the classification method could detect the mould core apple at the accuracy of 91.03%, and detect un-mould core apple at the accuracy of around 95.95%.
