摘　　要：应用改进的多尺度Retinex增强算法,对低能见度的红外图像进行图像增强,提高了原图像的对比度和像质,得到了目标区域的最佳视觉效果。理论分析和实验结果表明,该算法与维纳滤波、同态滤波等算法相比,有效地抑制了背景和噪声。该算法对红外图像增强后,图像对比度比前两种算法的对比度强。The improved multi-scale Retinex enhanced algorithm was applied to the infrared images of poor visibility, the contrast and quality of the original images can be improved, and the best visual effect of target area was achieved. The theoretical analysis and the result of the experiment indicate that this algorithm, compared with other algorithm such as Winner filter and homomorphism filter, can effectively suppress the background and noise. After enhancing the infrared images by using this algorithm, the images have better contrast than the first two algorithms.
