Visualization of Objects in Computer Tomography

The article examines methods for separating contours from computed tomography images. The important about the contours is that they are the places where a sharp change in the brightness of adjacent pixels takes place and to highlight them must be used so called “high-pass filters”. The article examines the separation of contours by first-order differential operators. An analysis of the existing methods of contour separation in images and the results obtained from their application on tomographic images is presented.
