Однако, когда распределение оттенков серого панхроматического изображения сильно сконцентрировано и имеет низкий контраст, качество слияния ухудшается. Чтобы преодолеть это ограничение, на этапе предварительной обработки мультиспектральных изображений вводится метод улучшения изображения, объединяющий управляемый фильтр и сигмоидную функцию. Управляемый фильтр эффективно сохраняет детали контуров, в то время как сигмоидная функция повышает контрастность, регулируя оттенки серого вблизи центра распределения. Для низкочастотных компонент предлагается стратегия слияния региональной энергии, регионального градиента и управляемой фильтрации, гарантирующая сохранение локальной энергии и информации о градиенте при сохранении деталей контуров. Для высокочастотных компонент применяется метод слияния на основе адаптивной импульсно-связанной нейронной сети. Экспериментальные результаты на двух общедоступных наборах данных подтверждают эффективность предлагаемого подхода, показывая увеличение стандартного отклонения до 83.49 и 52.69% по сравнению с неоптимальными результатами, а также увеличение среднего градиента до 78.49 и 60.64% по семи оценочным критериям.</p></abstract><trans-abstract xml:lang="en"><p>To tackle spectral distortion and spatial detail loss in remote sensing image fusion, this paper proposes a fusion method for panchromatic and multispectral images based on IHS transform and NSST decomposition. However, when the grayscale distribution of the panchromatic image is highly concentrated and has low contrast, the fusion quality declines. To overcome this limitation, an image enhancement technique combining the guided filter (GF) and sigmoid function is introduced in the preprocessing stage of multispectral images. The guided filter effectively preserves edge details, while the sigmoid function enhances contrast by adjusting grayscale values near the center of the distribution. For low-frequency components, a fusion strategy integrating regional energy, regional gradient, and guided filtering (RE-RG-GF) is proposed, ensuring that both local energy and gradient information are retained while maintaining edge details. For high-frequency components, an adaptive pulse-coupled neural network (PA-PCNN) fusion method is applied. Experimental results on two public datasets validate the effectiveness of the proposed approach, showing an increase in standard deviation by 83.49 and 52.69% over the suboptimal results, along with an average gradient increasing by 78.49 and 60.64%, respectively, across seven evaluation metrics.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>слияние изображений</kwd><kwd>сигмоидная функция</kwd><kwd>управляемая фильтрация</kwd><kwd>преобразование сдвиговой волны без понижения частоты дискретизации</kwd><kwd>преобразование IHS</kwd></kwd-group><kwd-group xml:lang="en"><kwd>image fusion</kwd><kwd>sigmoid function</kwd><kwd>guided filtering</kwd><kwd>non-downsampled shear wave transform</kwd><kwd>IHS transform</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">H.
