A new combinational scheme based on fusing and enhancing dual-energy X-ray hand luggage images is proposed in terms of X-ray image features. First

images are de-noised and fused with DWT (discrete wavelet transform)

and then enhanced in fuzzy space with fuzzy theory. The proposed method in this paper is compared with that based on GLG (gray level grouping)and HE (histogram equalization). Experimental results show that the new method can improve the image definition efficiently and have better generalization.
