An X-ray scanning and image processing have a vast

range of applications in the security. An image of a content of

some package being passed for example to an airplane or to the

court house may help to figure out if there are any dangerous

objects inside that package and to avoid possible threatening

situation. As the raw X-ray images are not always easy to analyze

and interpret, some image processing methods like an object

detection, a frequency resolution increase or a pseudocolouring

are being used. In this paper, we propose a pseudocoloring

improvement over material based approach. By addition of the

edge detection methods we fill and sharpen colour layers over

the image, making it easier to interpret. We demonstrate the

effectiveness of the methods using real data, acquired from a

professional dual energy X-ray scanner.
