若背景有雾时，红外图像中的目标会受到影响而变得比较模糊。雾的纹理是一种比较典型的自然纹理，利用灰度共生矩阵提取纹理特征图像的方法，对雾天获取的红外图像进行分析。通过实验证明了该方法对红外图像中(背景有雾时)目标的提取和识别有积极的作用。

The target of the infrared image becomes more blurred when the background has the fog. The fog texture is one kind of typical natural texture. Using gray co-occurrence matrix applied to extract the texture images based on pixel level, the infrared images taken on foggy days are analyzed. The experimental result shows that this method can play a positive role for the target extraction and identification of the infrared images taken on foggy days.
