Abstract:
In the paper is presented an approach for computed tomography (CT) images enhancement when focusing on the area of the brain. It consists of the following basic stages for image processing: selecting the region of interest (ROI), changing the brightness of the selected ROI by equalization of the local histogram and contrast increasing by morphological processing of the selected ROI. The aim is to solve problems with shape and contours of the investigated object and to improve the quality of the diagnostic computed tomography images. An effective algorithm was treatment on the base of investigation on the most suitable morphological operators. Some results of the experiments are presented, which were made by computer simulation in MATLAB environment.
