Аннотация
Введение. Представлен обзор современных методов глубокого обучения для обработки данных удаленной фотоплетизмографии. Рассмотрены архитектуры сверточных нейронных сетей, трансформеров, рекуррентных и генеративных моделей для предобработки видеосигнала, а также извлечения физиологически значимых параметров в условиях с артефактами, вызванными движением, изменением освещения или низким качеством видео. Выполнен анализ перспектив внедрения алгоритмов глубокого обучения в реальных медицинских сценариях на основе предложенных критериев с учетом существующих проблем интеграции, востребованности решений и валидации результатов. Метод. Выполнен обзор существующих методов глубокого обучения, которые используют видеосигнал для оценки сигнала фотоплетизмографии с использованием новых критериев для оценки методов, включая многомерность выходного сигнала фотоплетизмографии, открытость исходного кода и наличие информации о временных затратах, что является важным для их практического применения в реальном времени в медицинских учреждениях. Основные результаты. Показано, что методы глубокого обучения значительно превосходят традиционные подходы в задачах оценки физиологических параметров, в процессах диагностики сердечно-сосудистых заболеваний, а также предобработке видеосигнала. Выявлено, что большинство существующих решений, основанных на глубоком обучении, ограничиваются одномерным выходным сигналом из-за сложности получения многомерной разметки для обучения с учителем. Дополнительный анализ показал дефицит информации о временных и вычислительных затратах, что ограничивает практическое применение методов глубокого обучения в реальном времени. Представленная систематизация раскрывает ключевые термины, связанные с обработкой сигналов фотоплетизмографии: контактная фотоплетизмография, фотоплетизмография на основе видео, удаленная фотоплетизмография, визуализация фотоплетизмографии. Представлено описание подходов к сбору наборов данных, учитывающих концепции многомерности, многоканальности и мультимодальности сигналов. Обсуждение. Полученные результаты могут быть применены при разработке систем удаленного мониторинга здоровья, включая медицинские и бытовые устройства. Обзор будет полезен специалистам в области биомедицинской инженерии, медицинской информатики, а также разработчикам решений для анализа физиологических сигналов.

Ключевые слова: фотоплетизмография, визуализирующая фотоплетизмография, удаленная фотоплетизмография, многомерная фотоплетизмография, глубокое обучение, нейронные сети
