Восемь оптимальных длин волн выбраны с помощью нового метода выбора переменных — анализа совокупности переменных (VCPA). Текстурные особенности первых трех изображений с оценкой основных компонент получены с использованием матрицы совместной встречаемости уровней серого (GLCM) и локального двоичного шаблона (LBP). Разработан алгоритм случайной лягушки для выбора оптимальных текстурных особенностей для дальнейшего анализа. Для прогнозирования SSC яблока разработана модель регрессии опорных векторов (SVR), основанная на спектральных и текстурных характеристиках. Модель, основанная на восьми оптимальных длинах волн и девяти оптимальных характеристиках GLCM-изображений главных компонент, дает лучший результат с коэффициентом детерминации для прогноза (Rp2) 0.9193, среднеквадратичной ошибкой прогноза 0.2955 и отношением стандарта. Отклонение прогноза установлено на среднеквадратичную ошибку прогнозирования RPD = 3.50. Результаты показывают, что спектр в сочетании с оптимальными характеристиками GLCM из изображений основных компонент в сочетании с моделью SVR имеет потенциал для предсказания SSC яблока.</p></abstract><trans-abstract xml:lang="en"><p>We established prediction models based on the combination of spectral and different advanced image features to improve the prediction accuracy of solid-soluble content (SSC) of apple. Eight optimal wavelengths were selected using a new variable selection method called variable combination population analysis (VCPA). Image textural features of the first three principal component score images were obtained using a gray level co-occurrence matrix (GLCM) and a local binary pattern (LBP). Next, a random frog algorithm was developed to select optimal textural features for further analysis. A support vector regression (SVR) model based on spectral and different textural features was developed to predict the SSC of the apple. The model based on eight optimal wavelengths and nine optimal GLCM features of principal component images yielded the best result with the determination coefficient for prediction (Rp2) of 0.9193, root mean square error for prediction (RMSEP) of 0.2955, and the ratio of the standard deviation of the prediction set to the root mean square error of prediction (RPD) with a value of 3.50. These results revealed that the spectral combined with optimal GLCM features from principal component images coupled with the SVR model has the potential for prediction of the SSC of apple.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>гиперспектральное изображение</kwd><kwd>растворимое твердое вещество</kwd><kwd>текстурная характеристика</kwd><kwd>анализ совокупности переменных</kwd><kwd>случайная лягушка</kwd><kwd>модель регрессии опорных векторов</kwd></kwd-group><kwd-group xml:lang="en"><kwd>hyperspectral image</kwd><kwd>soluble solid content</kwd><kwd>textural feature</kwd><kwd>VCPA</kwd><kwd>random frog</kwd><kwd>SVR</kwd></kwd-group><funding-group><funding-statement xml:lang="en">The authors are grateful to Sichuan Province Department of Education (China) for support through the program of “Research on Apple Quality Nondestructive Testing Method Based on Hyperspectral Image Technology” (17ZB0333).
