Подавление шума в задачах визуализации

В сотрудничестве с группой вычислительной визуализации (Сomputational Imaging Group), Университета Тампере с 2014 года ведется широкий спектр исследований по разработке и алгоритмов шумоподавления и внедрения их в методы визуализации.

К настоящему времени совместно опубликовано 18 научных работ, среди которых 8 публикаций в журналах первого квартиля.
