Для повышения качества тонового отображения инфракрасных изображений при сжатии их динамического диапазона и упрощения управления характеристиками воспроизведения инфракрасных изображений предложеналгоритм преобразования динамического диапазона на основе адаптивного выравнивания гистограммыс инверсией краев. Сущность алгоритма состоит в двойном уменьшении динамического диапазона инфракрасного изображения с промежуточным растяжением, сжатием и наложением краев с инвертированием.Для выбора интервала яркости и степени его растяжения в предложенном алгоритме использовался коэффициент асимметрии. Алгоритм позволяет улучшить некоторые глобальные и интервальные показателикачества воспроизведения изображений за счет наложения краев гистограммы.</p></abstract><trans-abstract xml:lang="en"><p>The problem of compression of the dynamic range of infrared images is considered. To improve the quality of tone mapping of infrared images when their dynamic range is compressed and to simplify the control over the reproduction characteristics of infrared images, a dynamic range conversion algorithm based on adaptive histogram equalization with edge inversion is proposed. The essence of the algorithm consists in double reduction of the dynamic range of the infrared image with intermediate stretching, compression and overlapping of edges with inversion. To select the brightness interval and the degree of its stretching, the proposed algorithm uses the asymmetry coefficient. The algorithm makes it possible to improve some global and interval indicators of image reproduction quality by superimposing the edges of the histogram.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>уменьшение динамического диапазона изображений</kwd><kwd>повышение качества изображений</kwd><kwd>инфракрасные изображения</kwd><kwd>выравнивание гистограммы</kwd><kwd>управление формой гистограммы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>image dynamic range reduction</kwd><kwd>image enhancement</kwd><kwd>infrared images</kwd><kwd>histogram equalization</kwd><kwd>histogram shape control</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">Enhancement of Low Illumination Images Based on an Optimal Hyperbolic Tangent Profile / S.
