В работе представлен и валидирован интегрированный прототип конвейера и сегментации биомедицинских изображений, разработанная в рамках научного проекта (IRN: AP05132044). Экспериментальный протокол реализован на открытом наборе данных Heart Database (18 пациентов, 3D+t МРТ) с использованием экспертных масок эндокарда и 36 срезов (диастола/систола). Оценка качества проводилась по метрикам PSNR, SSIM, Dice и IoU. Сравнительный анализ включал пять режимов предобработки: none, Gaussian, wavelet, NLM и hybrid (wavelet + NLM + CLAHE). Показано, что метод NLM обеспечивает наилучшее качество шумоподавления (PSNR = 26,07±0,33 dB против 22,85±0,21 dB для baseline, p=1,46·10⁻¹¹, критерий Уилкоксона), тогда как максимальная точность сегментации достигается при hybrid-предобработке (Dice = 0,681±0,176 против 0,636±0,153 без предобработки, p=0,018). Проведён анализ «трудных» случаев, выявивший зависимость качества сегментации от контрастности эндокарда и геометрической сложности в различных фазах сердечного цикла. Полученные результаты демонстрируют статистически значимое влияние этапа предобработки на качество downstream-сегментации и подтверждают целесообразность использования комплексного конвейера «предобработка-сегментация-оценка» как инженерной основы для разработки систем клинического мониторинга. Предложенный подход ориентирован на воспроизводимую работу в условиях реальной неоднородности данных и может быть использован в качестве основы для дальнейшей интеграции в клинические информационные системы.</p></abstract><trans-abstract xml:lang="en"><p>Cardiovascular diseases remain the leading cause of mortality, which determines the relevance of developing robust methods for cardiac image analysis and patient monitoring. This paper presents and validates a prototype pipeline for automated preprocessing and segmentation of biomedical images, developed within the framework of a scientific project (IRN: AP05132044). The experimental protocol is implemented on the Heart Database dataset (18 patients, 3D+t MRI (three-dimensional with time dimension)), using expert endocardial masks and 36 slices (diastole/systole, 2 slices per patient). Performance evaluation was conducted using PSNR, SSIM, Dice, and IoU metrics. A comparative analysis was performed across five preprocessing modes: none, Gaussian, wavelet, NLM, and hybrid (wavelet + NLM + CLAHE). The results show that the NLM method achieves the best denoising performance (PSNR = 26.07±0.33 dB vs. 22.85±0.21 dB for the baseline, p = 1.46×10⁻¹¹, Wilcoxon test), while the highest segmentation accuracy is obtained with hybrid preprocessing (Dice = 0.681±0.176 vs. 0.636±0.153 without preprocessing, p = 0.018). An analysis of challenging cases revealed that segmentation performance is strongly influenced by endocardial contrast and geometric complexity across different phases of the cardiac cycle. The obtained results demonstrate a statistically significant impact of the preprocessing stage on downstream segmentation quality and confirm the feasibility of the integrated “preprocessing-segmentation-evaluation” pipeline as an engineering foundation for clinical frameworks. The proposed approach is designed for reproducible performance under real-world data heterogeneity and can serve as a basis for further integration into clinical information systems.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>биомедицинские изображения</kwd><kwd>кардиологический мониторинг</kwd><kwd>глубокое обучение</kwd><kwd>сегментация сердца</kwd><kwd>шумоподавление</kwd><kwd>фракция выброса</kwd><kwd>удаленное здравоохранение</kwd></kwd-group><kwd-group xml:lang="en"><kwd>biomedical images</kwd><kwd>cardiac monitoring</kwd><kwd>deep learning</kwd><kwd>heart segmentation</kwd><kwd>denoising</kwd><kwd>ejection fraction</kwd><kwd>remote healthcare</kwd></kwd-group><funding-group><funding-statement xml:lang="en">This research has been funded by the Science Committee of the Ministry of Science and Higher Education of the Republic of Kazakhstan (grant: №AP25794129 «Development of an Algorithm for Filtering and Preprocessing Biomedical Images for Cardiology Diagnostics»).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">World Health Organization.
