This paper describes a method to acquire actual image data of any material, which could be an explosive or parametric simulant, extract the X-ray features of the object, modify the images in a variety of controlled ways, and record new images. All of the augmented images can then be run through the emulator of the baggage screening system to explore the detection algorithm’s performance. This is similar to the method that was demonstrated over a decade ago, where the Transportation Security Laboratory developed a series of explosive simulants which spanned the X-ray feature space of mass density and effective atomic number, thus demonstrating the capability to effectively map out the performance of explosives detection systems in that feature space. In this paper, the concept has been expanded to include synthetic data, which is far more efficient than creating fully synthetic data and greatly diminishes the need to collect data using real explosives.
