Method for filling and sharpening false colour layers of dual energy X-ray images
Abstract
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.
