Table 6.

Testing results of the proposed method in comparison with those of the previous study on separated size classes (unit: %). 1st Testing Accuracy and 2nd Testing Accuracy mean the accuracies of the testing on the 1st and 2nd subsets of banknote images in the two-fold cross-validation method, respectively.
