1. A method for enhancing detail detectability in x-ray images, the method comprising:
- providing, via an x-ray inspection device, a positive x-ray image of a suitcase or other container under examination for one or more items of interest therein, the positive x-ray image having a brightness that is inversely related to x-ray beam attenuation;
subdividing the x-ray image into an object region and an empty region, the object region including the suitcase or other container under examination and the items of interest therein, and the empty region excluding the suitcase or other container under examination and the items of interest therein; and
darkening the empty region of the x-ray image relative to the object region.

10. An x-ray inspection system comprising:
-
an x-ray inspection device; a display device for displaying a positive x-ray image of a suitcase or other container under examination for one or more items of interest therein, the positive x-ray image having a brightness that is inversely related to x-ray beam attenuation, wherein the x-ray image is subdivided into an object region and an empty region, the object region including the suitcase or other container under examination and the items of interest therein, and the empty region excluding the suitcase or other container under examination and the items of interest therein; and a device for determining and darkening the empty region of the x-ray image relative to the object region. - View Dependent Claims (11, 12)

14. A non-transitory computer-readable medium comprising code, which, when executed by a machine, causes the machine to perform operations for enhancing detail detectability in x-ray images, the computer-readable medium comprising:
-
code for analyzing a positive x-ray image of a suitcase or other container under examination from an x-ray inspection device for one or more items of interest therein, the positive x-ray image having a brightness that is inversely related to x-ray beam attenuation; code for subdividing the x-ray image into an object region and an empty region, the object region including the suitcase or other container under examination and the items of interest therein, and the empty region excluding the suitcase or other container under examination and the items of interest therein; and code for darkening the empty region of the x-ray image relative to the object region.
