| 摘 要： | 提出了一种基于对比度受限自适应直方图均衡化(CLAHE)的X射线行李图像增强算法.首先使用一种背景区域快速填充方法降低背景噪声的干扰,然后采用CLAHE技术增强图像的对比度,最后采用一套组合锐化方案增强图像的细节.实验结果表明,使用所提方法能够快速有效地增强X射线行李图像的对比度,突出行李物品的细节.

| Abstract: | A contrast limited adaptive histogram equalization(CLAHE)based X-ray luggage image enhancement algorithm was proposed. First,a fast background padding method was used to reduce interfering effect of noise in the background. Next,CLAHE technique was adopted for image contrast enhancement. In the end,a combined sharpening method was employed to enhance image details. The experimental results show that the proposed algorithm is fast and effective in enhancing the contrast of X-ray luggage images and highlighti... |
