摘　　要：云层的遮挡作用对遥感影像的处理和分析带来一定的困难,依据影像中云雾处于相对低频部分,景物处于相对高频的特性,应用同态滤波的方法实现对云层低频分量的抑制,从而达到去除遥感影像中的云雾影响的目的。Clouds in remote sensing imagery make it difficult to process. According to the characteristic of clouds at lower frequency and landscape at higher frequency in remote sensing imagery, the paper realizes the removal of clouds in the remote sensing imagery by using the homographic filtering to the lower frequency.

关 键 词：影像增强 同态滤波 云雾去除 遥感图像处理系统
