Abstract
Рассмотрена задача выбора вида и параметров сигмоидальной функции нелинейного контрастирования метода повышения качества визуализации маммограмм IMRI-MAM, а также выбора критерия оценки качества изображения. Выполнена экспериментальная проверка визуального качества обработанных цифровых маммограм с помощью предложенного критерия.
Experimental verification of the IMRI-MAM method of the visualization quality improvement of mammograms with using exponential sigmoid function was performed. 350 mammograms obtained with the digital X-ray mammography complex SYMA (manufactured by "Radmir", Kharkov, Ukraine) were processed using the IMRI-MAM method. Subjective assessment of the experts showed a significant quality improvement of the processed images, which is also confirmed by objective assessments of the images quality. Further studies are aimed at generalization of the IMRI-MAM method to handle different kinds of radiographic images.
