Abstract :
In this paper preliminary results on quality grading of ´Jonagold´ apples are presented. Apple area is divided into subregions from where various features are extracted. Another segmentation method, ´geometric centers´, is also introduced. Effects of direct vs. separate principle components analysis and k-nearest neighbor vs. neural network classifiers on the performance are discussed.
