摘　　要：针对现有的图像增强算法对噪声比较敏感,容易产生颜色失真的现象,提出了一种避免颜色失真的图像增强算法。在分析对数图像处理模型的基础上,提出了一种正切图像处理模型,从调色板中提取颜色信息,避免颜色失真,该算法简单、易于实现,对噪声具有一定的抑制作用,可以增强和保留图像的细节信息。实验结果表明,所提算法明显优于其他图像增强算法。For the existing image enhancement algorithm is sensitive to noises and easy to create color distortion, an image enhance- ment algorithm avoiding color distortion is proposed. Under analysis of LIP model, a TIP model is proposed. Color information is extracted from the palette to avoid color distortion. This algorithm is simple, easy to implement, and detail signals of image can be preserved and enhanced when noise is restrained effectively. This algorithm is obviously better than other image enhance- ment algorithms through the experiment.
