В статье предлагаются методика сравнения нейросетевых дескрипторов и выбор оптимального нейросетевого метода поиска схожих анатомических областей, гибридный алгоритм поиска, основанный на совместном использовании традиционных и нейросетевых дескрипторов. Такой алгоритм позволил улучшить результат нейросетевого поиска анатомических паттернов, выраженный в миллиметрах до искомого слоя, на 47 % для первых десяти найденных изображений класса сердца и на 18 % – для изображений с позициями от 10 до 100. Итоговый результат поиска анатомической области улучшился по сравнению с традиционными подходами на 9,7 % для найденных изображений с позициями от 10 до 100 и на 2 % – для первых десяти найденных изображений.</p></abstract><trans-abstract xml:lang="en"><p>The search for anatomical layers in lung CT images will simplify the task of diagnosis and treatment planning, as well as automate the process of image partitioning when preparing a training sample. The paper proposes a methodology for comparison of neural network descriptors and selection of an optimal neural network method for searching for similar anatomical regions. Neural network approaches are compared with traditional methods and a hybrid search algorithm based on the joint use of traditional and neural network methods is proposed. Using the proposed algorithm, the neural network search result for anatomical patterns, expressed in mm to the searched layer, was improved by 47 % for the first ten heart-class images found and by 18 % for images with positions from 10 to 100. The final anatomical region search result was improved over using traditional approaches by 9.7 % for retrieved images with positions from 10 to 100 and by 2 % for the first ten retrieved images.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>матрицы совместной встречаемости</kwd><kwd>нейросетевые дескрипторы</kwd><kwd>глубокое обучение</kwd><kwd>сверточные нейронные сети</kwd><kwd>изображения компьютерной томографии</kwd></kwd-group><kwd-group xml:lang="en"><kwd>co-occurrence matrices</kwd><kwd>neural network descriptors</kwd><kwd>deep learning</kwd><kwd>convolutional neural networks</kwd><kwd>computed tomography images</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при поддержке Белорусского республиканского фонда фундаментальных исследований (проект № Ф22КИТГ-001).
