| 摘 要： | 针对X射线图像的特点，提出了一种新的X射线手提行李图像增强方法。首先，应用离散小波变换（DWT）对图像进行去噪、融合，然后，结合模糊理论在模糊空间实现图像增强。同时将本文方法与基于灰度分组(GLG)的增强方法、基于直方图均衡 (HE)的增强方法做了比较，实验结果表明,本文方法可以有效地提高图像的清晰度，具有较好的推广能力。

| Abstract: | 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. |
