Paper Abstract

Baggage scanning systems are used for detecting the presence of explosives and other prohibited items in baggage at security checkpoints in airports. However, the CT baggage images contain projection noise and are of low resolution. This paper introduces a new enhancement algorithm combining alpha-weighted mean separation and histogram equalization to enhance the CT baggage images while removing the background projection noise. A new enhancement measure is introduced for quantitative assessment of image enhancement. Simulations and a comparative analysis are given to demonstrate the new algorithm's performance.
