The purpose of this study is to determine the optimal wavelet-based feature extraction technique based for rice growth stage classification. Data are obtained from the Badan Pengkajian dan Penerapan Teknologi (BPPT). We implemented two decomposition approach i.e. standard wavelet decomposition and wavelet packet analysis with coif1, coif2, coif3, db2, db3 and haar as the wavelet basis. The level of decomposition on wavelet decomposition begins from 3 to 11, while on wavelet packet analysis starts from the decomposition level 3 to 6. From each subband we extraced the following features: mean, median, skewness, kurtosis, residual energy, energy, standard deviation, and variance. We used k-nearest-neighbor, naive bayes, support vector machine and decision tree as the classifier. The highest accuracy of the wavelet decomposition is 90.41% with db2 as wavelet basis and 11 level of decomposition using support vector machine as the classifier. Wavelet packet analysis approach gives 80.17% accuracy on Haar wavelet basis and 3 level decomposition using decision tree as the classifier. Based on the experimental results, support vector machine and decision tree have better performance than k-nearest-neighbor and Naive Bayes on 77 of total 84 trials. © 2017 Global IT Research Institute - GiRI.
