Исследована возможность использования ближней ИК спектроскопии для оценки содержания азота в каучуковом дереве в естественной среде. Метод разработан на основе алгоритма обратного распространения ошибки и алгоритма Адабуст. Результаты имитационного эксперимента показали, что при использовании предлагаемого метода достигается удовлетворительная эффективность классификации - количество правильно классифицированных образцов 92.98%.

Foliar nitrogen (N) is an important index to evaluate the content of nitrogen in rubber trees. Hence, a fast way utilizing the spectroscopy to estimate the nitrogen content level of the rubber tree under natural environment has been preliminarily investigated in this paper. The combined features strategy is adopted in this study. The evaluation model is developed by back propagation (BP) algorithm and Adaboost algorithm. The results of simulation experiment show that satisfactory classification performance has been achieved using the proposed model and the percentage of samples correctly classified by the proposed model in the validation set is 92.98%.
