Table 1 summarizes the classification results of the proposed method using fixed interval data reduction method with different number of data points. Overall, our results showed that the proposed relatively simple classification algorithm based on contour matching performed very well (100% for banana, 91.3% for irregular, and 92.9% for good when using 50 data points). According to our experiments, a reduced data point set of as few as 50 contour points was sufficient to retain the important shape features for comparison.
