Неотрицательность разреженной матрицы сокращает время расчета и повышает эффективность. Для проверки алгоритма n-SMT образцы листьев элеутерококка колючего, пораженных заболеванием, классифицированы для идентификации различных частей листьев после уменьшения размерности. Наряду с n-SMT для всех образцов применен алгоритм вычисления минимальной доли шума. Сравнивается время работы двух алгоритмов и проверяется точность классификации с помощью алгоритма n-SMT.</p></abstract><trans-abstract xml:lang="en"><p>A variety of pictures in hyperspectral fields requires a reduction in dimensionality, which often needs unique algorithms such as principal component analysis and minimum noise fraction (MNF). This article investigates the improved method of non-negative sparse matrix transformation based on the maximum likelihood covariance estimation and the Frobenius norm to better achieve dimensionality reduction. Non-negativity is presented based on the sparse matrix, which reduces the calculation time and improves efficiency. In order to verify the non-negative sparse matrix transforms (n-SMT) algorithm, samples eroded by disease were selected in the experiment and classified to identify the different parts of leaves after dimension reduction. Besides the n-SMT method, the MNF algorithm is also applied to all the samples. This article compares the two algorithms’ operating time and verifies the accuracy of classification after the n-SMT algorithm.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>неотрицательная разреженная матрица</kwd><kwd>матричное преобразование</kwd><kwd>гиперспектральное изображение</kwd><kwd>обработка изображений</kwd></kwd-group><kwd-group xml:lang="en"><kwd>non-negative sparse matrix</kwd><kwd>matrix transformation</kwd><kwd>hyperspectral image</kwd><kwd>image processing</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">X.
