На данных масштабного набора Sparsely Annotated Region and Organ Segmentation обучено и протестировано 10 моделей. Получены значения коэффициента схожести Дайса и пересечения над объединением в диапазонах 0,9339–0,9421 и 0,8737–0,8885. Применение трехканального подхода к формированию входных данных повысило точность моделей четырех архитектур из пяти рассмотренных. Обученные модели могут применяться для быстрой и точной разметки мышечной ткани в процессе диагностики.</p></abstract><trans-abstract xml:lang="en"><p>The results of a study of a preprocessing influence method based on the formation of three-channel images on the accuracy of muscle tissue segmentation models on the computed tomography scans corresponding to the levels of the vertebrae of the thoracic and lumbar spine are presented. Ten models have been trained and tested on the Sparsely Annotated Region and Organ Segmentation dataset. The values of the Dice similarity coefficient and the Intersection over Union in the ranges of 0.9353–0.9421 and 0.8737–0.8885 were obtained. The use of a three-channel approach to the formation of input data increased the accuracy of models of four of the five architectures considered. Trained models can be used to quickly and accurately annotate muscle tissue during the diagnostic process.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>компьютерное зрение</kwd><kwd>сегментация</kwd><kwd>компьютерная томография</kwd><kwd>мышечная ткань</kwd><kwd>диагностика</kwd><kwd>U-Net</kwd></kwd-group><kwd-group xml:lang="en"><kwd>computer vision</kwd><kwd>segmentation</kwd><kwd>computed tomography</kwd><kwd>muscle tissue</kwd><kwd>diagnostics</kwd><kwd>U-Net</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">Теплякова А.Р., Шершнев Р.В., Старков С.О., Агабабян Т.А., Кукарская В.А.
