Abstract :
We propose a new scheme for the fusion of backscatter images and transmission images in X-ray luggage inspection systems. Our fusion algorithm is based on multi-scale decomposition of backscatter/transmission images under the weighted least square (WLS) framework. A two-step algorithm is then applied to obtain enhanced final fusion image suitable for human inspection. Experimental results show our algorithm can combine useful cues from both sources of images with rich image details.
