Abstract

Изобретение относится к области обработки цифровых изображений и может быть использовано для решения задач подавления шума цифровых изображений, полученных с помощью высокоэнергетического излучения, в том числе рентгеновского. Более конкретно, данное изобретение предназначено для подавления шума цифровых рентгенограмм. Задача настоящего изобретения - разработка способа подавления шума цифровых рентгенограмм с расширенной функциональностью, в частности, с возможностью уменьшения уровня остаточного шума и артефактов в виде разрывов непрерывности, направленных вдоль локальной ориентации границ объектов в текстурированных областях изображений; с возможностью уменьшения уровня остаточного низкочастотного шума; а также исключением пересглаживания (чрезмерной фильтрации) мелких деталей. Технический результат - повышение качества обработки цифровых рентгенограмм.
