| 摘 要： | 雾天获取的图像,掩盖了部分需要的真实信息.针对这类图像,给出了应用强化边缘的方法进行处理,主要采用多尺度边缘提取方法获得图像边缘;用小波阈值去噪法对图像进行消噪处理;为了避免传统方法产生的块状现象,最后用三次样条插值对图像进行平滑处理.

| Abstract: | The real information needed in the mist image has been covered.The method of reinforced the edges has been used for processing the mist image.The image edge is obtained mainly by using the multi-scale edge extraction method,using wavelet threshold denoising method for the image; finally using 3-spline interpolation to smooth and remove possible lump phenomena in order to avoid creating massive phenomenon by the traditional method. |

| Keywords: | edge extraction multi-scale wavelet analysis threshold denoising 3-spline interpolation histogram equalization |
